qcacld-3.0: Rename pMac in WMA

Per the Linux coding style "mixed-case names are frowned upon" and
"so-called Hungarian notation [...] is brain damaged." One identifier
used extensively throughout the driver that violates both of these
tenants is "pMac." In order to be compliant with the Linux coding
style there is a campaign to rename all instances of this identifier.

For this change rename all instances of "pMac" to "mac" in:
wma_api.h
wma_if.h
wma_internal.h
wma_types.h
wlan_qct_wma_legacy.c
wma_data.c
wma_dev_if.c
wma_main.c
wma_scan_roam.c
wma_utils.c
