afs: Handle the VIO and UAEIO aborts explicitly

When processing the result of a call, handle the VIO and UAEIO 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.
