nl80211: Indicate SUITE_B_192 capa only when CCMP-256/GCMP-256 supported

SUITE_B_192 AKM capability was indicated for all devices using the
nl80211 driver (without the QCA vendor specific AKM capability
indication). However, some devices can't handle Suite B 192 due to
insufficient ciphers supported. Add a check for CCMP-256 or GCMP-256
cipher support and only indicate SUITE_B_192 capability when such cipher
is supported. This allows compiling with CONFIG_SUITEB192 and still get
proper response to the 'GET_CAPABILITY key_mgmt' command. Under Android
it can also serve as a dynamic way for HAL to query platform for
WPA3-Enterprise 192-bit support.
