[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.
