wifi: iwlwifi: mvm: fix the TXF mapping for BZ devices

Browse Source 
Those devices' fifos are numbered differently.
Because of that, we were looking at the size of the VO fifo size to
determine the size of the A-MSDU which led to a lower throughput.

Note that for those devices the only user of the AC -> fifo mapping is
the size limitation of A-MSDU.
