hd-geometry: Clean up confusing use of prior translation hint
When hd_geometry_guess() picks a geometry, it also picks the
appropriate translation, but only when the prior translation hint is
BIOS_ATA_TRANSLATION_AUTO. Looks wrong, because such a prior
translation would be passed to the BIOS whether it's suitable for the
geometry or not.
Fortunately, that can't happen. There are just two ways for the
translation hint to get set to something other than
BIOS_ATA_TRANSLATION_AUTO: drive_init() on behalf of -drive trans=...,
and hd_geometry_guess(). Both set it only when they also set a valid
geometry hint, i.e. one with a non-zero number of cylinders.
Since hd_geometry_guess() returns right away when it finds a valid
geometry hint, translation can only be BIOS_ATA_TRANSLATION_AUTO in
the remainder of the function.
Assert this, and simplify accordingly.

vvfat: Do not clobber the user's geometry
vvfat creates a virtual VFAT filesystem with a certain logical
geometry that depends on its options. It sets the "geometry hint" to
this geometry. It is the only block driver to do this.
The geometry hint is about about *physical* geometry, and used only by
certain hard disk device models.
vvfat's hint is normally invisible for device models, because
bdrv_open() puts a raw format on top of vvfat's fat protocol. That
raw format is where drive_init() puts the user's geometry (if any),
and where the device model gets it from.
Nobody complained, because the default physical geometry is the same
as vvfat's logical geometry:
opts LCHS def. PCHS
1024,16,63 same
:32: 1024,16,63 same
:16: 1024,16,63 same
:12: 64,16,63 same
Except when you specify :floppy:
opts LCHS def. PCHS
:floppy: 80, 2,36 5,16,63
:32:floppy: 80, 2,36 5,16,63
:16:floppy: 80, 2,36 5,16,63
:12:floppy: 80, 2,18 2,16,63
Silly thing to do for use with a hard disk.
However, the "raw" format can be suppressed by adding an
redundant-looking "format=vvfat" to "file=fat:FOO". Then, vvfat's
hint clobbers the user's geometry, i.e. -drive options cyls, heads,
secs get silently ignored. Don't do that.
No change without format=vvfat. With it, the user's hard disk
geometry (-drive options cyls, heads, secs) is now obeyed, and the
default hard disk geometry with :floppy: now matches the one without
format=vvfat.

vvfat: Fix partition table
Unless parameter ":floppy:" is given, vvfat creates a virtual image
with DOS MBR defining a single partition which holds the FAT file
system. The size of the virtual image depends on the width of the
FAT: 32 MiB (CHS 64, 16, 63) for 12 bit FAT, 504 MiB (CHS 1024, 16,
63) for 16 and 32 bit FAT, leaving (64*16-1)*63 = 64449 and
(1024*16-1)*64 =
1032129 sectors for the partition.
However, it screws up the end of the partition in the MBR:
FAT width param. start CHS end CHS start LBA size
:32: 0,1,1 1023,14,63 63
1032065
:16: 0,1,1 1023,14,55 63
1032057
:12: 0,1,1 63,14,55 63 64377

1032129 or 64449 sectors. Oops.
