x86/PCI: Tidy E820 removal messages
These messages:
clipped [mem size 0x00000000 64bit] to [mem size 0xfffffffffffa0000 64bit] for e820 entry [mem 0x0009f000-0x000fffff]
aren't as useful as they could be because (a) the resource is often
IORESOURCE_UNSET, so we print the size instead of the start/end and (b) we
print the available resource even if it is empty after removing the E820
entry.
Print the available space by hand to avoid the IORESOURCE_UNSET problem and
only if it's non-empty. No functional change intended.
