bss_config->key_mgmt specifies the AKM suites that are usable in hardware. This variable is set to specific values while iterating over the advertised AKM suites. This means the final value of the variable depends on the order of the entries in the AKM suites array. Instead of setting the variable, just set the relevant bits in the key_mgmt bit field to make us independent of the order of entries. This behaviour is derived from the downstream driver that does the same. Also, set bss_config->key_mgmt to zero explicitly right before the loop. bss_config has been zero allocated by the caller already, but do so again to safe the reader from following the code path.
