qcacld-3.0: Properly configuring OpClass into TDLS Peer

Browse source 
OpClass in TDLS peer is configured using gTDLSPrefOffChanNum
and gTDLSPrefOffChanBandwidth INIs. Values of OffChanBandwidth
INI can't distinguish 40+ and 40- BW which is required to fetch
the correct Opclass for a given channel from regdb. Adding
function which will convert OffChanBandwidth value into required
value before fetching opclass. This is required for TDLS 5.9 Cert
Test Case.
