mwl8k: refactor some conditionals for clarity
CC [M] drivers/net/wireless/mwl8k.o
drivers/net/wireless/mwl8k.c: In function ‘mwl8k_bss_info_changed’:
drivers/net/wireless/mwl8k.c:3290:2: warning: ‘ap_mcs_rates’ may be used uninitialized in this function [-Wmaybe-uninitialized]
memcpy(cmd->mcs_set, mcs_rates, 16);
^
drivers/net/wireless/mwl8k.c:4987:5: note: ‘ap_mcs_rates’ was declared here
u8 ap_mcs_rates[16];
^
The warning was bogus. But the conditionals were rather complicated,
with multiple redundant checks. This consolidates the checking and
makes it more readable IMHO.
