qcacld-3.0: Add logic to ignore PMF check for STA test mode

In testbed STA mode the RSNE may not match with APUT and thus
driver fails to filter AP from scan cache as PMF capability
mismatch.

With this change driver will ignore PMF capability check and
proceed with connection to send auth and assoc to APUT.
