agn and 3945 has different statistics_notif data structure; since 3945
has it statistics_notif data structure inside the _3945 portion of
iwl_priv, it make sense to move the agn statistics_notif into _agn
portion.

When station management calls to ucode return
an error we could previously do nothing, but
now that almost all calls are synchronous we
can actually let the error bubble up. Use EIO
as the error as it best indicates a problem
with the device.

Now that the ampdu_action callback can sleep,
we can use the mutex to properly protect the

they should happen.

Also, add some sleep and mutex debugging so
we won't call any of the functions that now
require being able to sleep and/or the mutex
to be held in an invalid context.

Currently, detection in hwsim and ath9k can
detect that two sw scans are in flight at the
same time, which isn't really true. It is
caused by a race condition, because the scan
complete callback is called too late, after
the lock has been dropped, so that a new scan
can be started before it is called.

It is also called too early semantically, as
it is currently called _after_ the return to
the operating channel -- it should be before
so that drivers know this is the operating
channel again.

Reviewed RX descriptor functions against the HAL sources. Some minor changes:

  - check size before making changes to the descriptor

  - whitespace

  - add comments about 5210 timestamps. this needs to be adressed later!

  - FIFO overrun error only available on 5210

  - rs_phyerr should not be OR'ed

  - clear the whole ath5k_rx_status structure before using, instead of
    zeroing specific fields.
