cluster/afr: During name heal, propagate EIO only on gfid or type mismatch
Backport of: http://review.gluster.org/#/c/12973/
When the disk associated with a brick returns EIO during lookup, chances are
that name heal would return an EIO because one of the syncop_XXX() operations
as part of it returned an EIO. This is inherently treated by afr_lookup_selfheal_wrap()
as a split-brain and the lookup is aborted prematurely with EIO even if it
succeeded on the other replica(s).
