[AFS]: Adjust the new netdevice scanning code
Adjust the new netdevice scanning code provided by Patrick McHardy:
(1) Restore the function banner comments that were dropped.
(2) Rather than using an array size of 6 in some places and an array size of
ETH_ALEN in others, pass a pointer instead and pass the array size
through so that we can actually check it.
(3) Do the buffer fill count check before checking the for_primary_ifa
condition again. This permits us to skip that check should maxbufs be
reached before we run out of interfaces.
