Only clear unmasked interrupts. If an interrupt is temporarily masked,
its pending events need to be processed later, even if another interrupt
happened in the mean time.

If a MCU timeout occurs before a hw restart completes, another hw restart
is scheduled, and the station state gets corrupted.
To speed up dealing with that, do not issue any MCU commands after the first
timeout, and defer handling timeouts until the reset has completed.
Also ignore errors in MCU commands during start/config to avoid making user
space fail on this condition. If it happens, another restart is scheduled
quickly, and that usually recovers the hardware properly.

Sending beacons to the hardware always happens in batches. In order to
speed up beacon processing on usb devices, this patch splits out common
code an calls it only once.
Beacons are sequentially written into the beacon memory area, by
tracking its usage with the dev->beacon_data_count. For MBSS support
and buffered traffic dev->beacon_data_count is used to create the bypass
mask.
The code is also adapted for the mmio part of the driver, but should not
have any performance implication there.
MBSS tests were performed with AVM AC860 USB NIC with temporary support
for 5 BSS'. Different combinations of active vifs were created and
brought up. Afterwards connection and data transfer was tested for the
announced BSS'.
