Subject: [PATCH 13/41] afs: Handle the VIO abort explicitly

When processing the result of a call, handle the VIO abort specifically
rather than leaving it to a default case.  Rather than erroring out
unconditionally, see if there's another server if the volume has more than
one server available, otherwise return -EREMOTEIO.
