ath10k: leave MMIC generation to the HW 

Apparently HW doesn't require us to generate MMIC
for TKIP suite.

Each frame was 8 bytes longer than it should be
and some APs would drop frames that exceed 1520
bytes of 802.11 payload. This could be observed
during throughput tests or fragmented IP traffic.
