qcacld-3.0: Rename mac in __lim_counter_measures()

An upcoming campaign will rename all instances of pMac to mac in the
driver. In function __lim_counter_measures() there is already a local
variable named mac, so the pMac renaming will cause a conflict. In
order to avoid the conflict rename the existing local variable.
