qcacld-3.0: Reset 11i parameters in RSO command

Browse source 
PMK caching and OKC is valid only in non CCKM roaming scenarios.
If these parameters passed to FW in CCKM case then device may add the
PMKID in reassoc request frames which is not expected.
So reset 11i parameters in RSO command if the authentication type is
CCKM.
