iwlwifi: mvm: use a cast to calculate the last seqno from the next one
If the next seqno returned by the firmware is 0, we return an error
(-16) in the iwl_mvm_get_last_nonqos_seq() function. This is because
we return an integer and don't use any casting when calculating the
last seqno from the one we received. Fix this by using a cast to u16
when doing the calculation, so we return 0xfff0, as we should.
