Subject: [PATCH v3 1/3] wifi: mwifiex: simplify WPA flags setting

The WPA flags setting only depends on the wpa_versions bitfield and not
on the AKM suite, so move it out of the switch/case to simplify the code
a bit. Also set bss_config->protocol to zero explicitly. This is done
only to make the code clearer, bss_config has been zero alloced by the
caller, so should be zero already. No functional change intended.
