fils: Ensure capability checks are consistent

Browse Source 
iwd supports FILS only on softmac drivers.  Ensure the capability check
is consistent between wiphy and netdev, both the softmac and the
relevant EXT_FEATURE bit must be checked.

CMD_EXTERNAL_AUTH could potentially be used for FILS for FullMAC cards,
but no hardware supporting this has been identified yet.
