mount/fuse : Fix parsing of vol_id for snapshot volume

For supporting sub-dir mount, we changed the volid. Which means anything
after a '/' in volume_id will be considered as sub-dir path.

But snapshot volume has vol_id stracture of /snaps/<volname>/<snapname>
which has to be considered as during the parsing.

Note 1: sub-dir mount is not supported on snapshot volume
Note 2: With sub-dir mount changes brick based mount for quota cannot be
        executed via mount command. It has to be a direct call via glusterfs
