qcacld-3.0: Rename pMac in PE & SME RRM files

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:
rrm_api.h
rrm_api.c
sme_rrm_api.h
sme_rrm.c
