In rvu_mbox_handler_cgx_mac_addr_get()
and rvu_mbox_handler_cgx_mac_addr_set(),
the msg is expected only from PFs that are mapped to CGX LMACs.
It should be checked before mapping,
so we add the is_cgx_config_permitted() in the functions.

Fixes: 96be2e0da85e ("octeontx2-af: Support for MAC address filters in CGX")

Thanks, applied. In the future there is no need to resend to add the
