staging: wfx: simplify hif_set_association_mode()

Browse Source 
The file hif_tx_mib.c expects to contain functions that format messages
for the hardware. It is unexpected to find function that manipulate
RCU and structures from mac80211.

Keep hif_set_association_mode() with the code necessary for message
formatting and relocate the smart part in wfx_join_finalize().
