mwifiex: update correct dtim_period in dump_station()
Earlier we were using dtim period extracted from scan response
buffer provided by FW in scan operation. But it is observed that
sometimes the buffer doesn't contain dtim period tlv, and wrong
value (0) was sent to user space.
After association FW will start listening to beacon frames of
connected AP and store dtim period. Therefore we can get it from
FW in dump_station() instead of using wrong value obtained in
scanning.
Redundant code after adapting new approach for dtim period is
also removed in this patch.
