iwlwifi: mvm: support new BAID allocation command
Due to some rearchitecting inside the firmware, a new BAID
allocation command is being introduced. Support it. Note
that with it the firmware no longer returns "no space" but
will crash instead, so check for that before sending the
command to the firmware.
