qcacld-3.0: Introduce sap_get_mac_context()

Browse source 
Currently the macro CDS_GET_HAL_CB() is used throughout the SAP to
retrieve an opaque handle for the MAC context. This name is an
anachronism given that the HAL layer was moved to firmware many
generations ago. In addition, since the SAP module is internal to the
UMAC, it should normally not be dealing with the opaque handle but
should instead be dealing directly with the MAC context. Finally, per
the coding style, "inline functions are preferable to macros
resembling functions."

To address these issues introduce sap_get_mac_context(), a new inline
function, to replace the current usage of CDS_GET_HAL_CB().

Subsequent changes will actually perform the replacement.
