brcmfmac: fix invalid permanent MAC address in wiphy 

When host driver retrieves mac addresses from dongle, driver copies memory
from drvr->mac to perm_addr. But at the moment, drvr->mac is all zero
array which causes permanent MAC address in wiphy is all zero as well.
To fix this, we set drvr->mac before setting perm_addr.
