qcacld-3.0: Rename hdd_is_valid_mac_address() pMacAddr param

hdd_is_valid_mac_address() currently takes a parameter named pMacAddr.
Per the Linux coding style "mixed-case names are frowned upon" and
"so-called Hungarian notation [...] is brain damaged" so rename the
parameter to mac_addr to conform to the naming convention. As part of
the cleanup relocate the documentation so that the interface is
documented, not the implementation.
