Currently, host driver rejects any concurrent session with other
security modes(e.g. NAN) when WAPI is present. This is due to a
limitation on older platforms. But newer platforms(e.g. Lithium
architecture) support WAPI+other security modes concurrently.
Firmware advertises service capability WAPI_CONCURRENCY_SUPPORTED if it
supports other security modes when WAPI is active. Get the capability
and accept/reject concurrent sessions.
