qcacmn: Code movement to enable multipass support without WDS

Browse Source 
Currently the code to support Multipass on SAP is
present along with the code to support WDS. Hence with
the code in its current state, we will not be able to
enable Multipass support without enabling WDS.

Move the multipass support code out of the WDS support
code, to be able to enable Multipass for chipsets which
do not use WDS.
