cfg80211: avoid sending spurious deauth to userspace

cfg80211: remove warning in deauth case
we assumed that drivers never give us spurious deauth
frames because they filter them out based on the auth
state they keep track of. This turned out to be racy,
because userspace might deauth while the AP is also
sending a deauth frame, so the warning was removed.
However, in that case we should not tell userspace
about the AP's frame if it requested deauth "first",
where "first" means it came to cfg80211 first.

ar9170: small misc changes
This patch aggregates a bunch of small random changes
that won't fit really anywhere else properly.
1. move tid-locating macro into a separate function.
2. remove redundant NULL check.
3. add modulation mask definition

ar9170: remove redundant frame flags
The flags in question were once useful for debugging.
Time has passed and now they do nothing more than
duplicating txinfo->flags.

ar9170: improve network latency
AR9170 has the bad habit of choking when traffic builds up.
Tests have shown that this can partially be attributed to
a huge buildup of backlogged frames.

mac80211: trace interface name
It's not all that useful to have the vif/sdata pointer,
we'd rather refer to the interfaces by their name.

mac80211: reduce reliance on netdev
For bluetooth 3, we will most likely not have
a netdev for a virtual interface (sdata), so
prepare for that by reducing the reliance on
having a netdev. This patch moves the name
and address fields into the sdata struct and
uses them from there all over. Some work is
needed to keep them sync'ed, but that's not
a lot of work and in slow paths anyway.
In doing so, this also reduces the number of
pointer dereferences in many places, because
of things like sdata->dev->dev_addr becoming
sdata->vif.addr.

mac80211: make station management completely depend on vif
The station management currently uses the virtual
interface, but you cannot add the same station to
multiple virtual interfaces if you're communicating
with it in multiple ways.
This restriction should be lifted so that in the
future we can, for instance, support bluetooth 3
with an access point that mac80211 is already
associated to.
We can do that by requiring all sta_info_get users
to provide the virtual interface and making the RX
code aware that an address may match more than one
station struct. Thanks to the previous patches this
one isn't all that large and except for the RX and
TX status paths changes has low complexity.
