feature/gfid-access: Fix nameless lookup on ".gfid"

Backport of http://review.gluster.org/14773

Problem:
In geo-replication, if the data copied from .snaps
directory to the master, the first set of copy after
uss is enabled doesn't get sync to slave.

Cause:
Enabling uss results in graph switch. So when the
lookup comes on "0x00...0d/gfid1" on new graph,
("0x00...0d' being the gfid of virtual directory
 ".gfid"), it fails as gfid-access xlator doesn't
handle it.

Fix:
Handle nameless lookup on ".gfid" in gfid-access
xlator.
