Since the commit below, iwldvm sends the FLUSH command to
the firmware. All the devices that use iwldvm have a
firmware that expects the _v3 version of this command,
besides 5150.
5150's latest available firmware still expects a _v2 version
of the FLUSH command.
This means that since the commit below, we had a mismatch for
this specific device only.
This mismatch led to the NMI below:

Implement proper WoWLAN wakeup and query the wakeup
reasons, then report them to userspace.
Note that this is tricky: a firmware bug (that has
been fixed in later versions) means that the status
command response isn't properly closed in hardware
and thus won't arrive at the host. Sending another
command after it closes the status response but the
next command gets stuck, etc. We reset the device
after querying though, so this is not a big issue,
just makes for strange code.

The flush_control parameter to iwlagn_txfifo_flush
is passed as an internal value (context flags) and
then sent to the device, that can't be right.
Fix the confusion by removing the parameter, always
use IWL_DROP_ALL that is redefined according to the
firmware API in the flush control.

The flush command really flushes queues, not
FIFOs, and the first 32 bits indicate the
queues to flush, not FIFOs. Change the command
accordingly.

Since the firmware will give us an A-MPDU bit and
only a single PHY information packet for all the
subframes in an A-MPDU, we can easily report the
minimal A-MPDU information for radiotap.

The device only supports a maximum of three
antennas, and only three bits are used, the
fourth bit is the A-MPDU indicator.
The only consequence of this is reporting
invalid information in radiotap, so this
isn't an important change.

Since we're working on another mode/driver
inside iwlwifi, move the current one into a
