mgmt/glusterd: use proper path to the volfile
Till now, glusterd was generating the volfile path for the snapshot
volume's bricks like this.
/snaps/<snap name>/<brick volfile>
But in reality, the path to the brick volfile for a snapshot volume is
/snaps/<snap name>/<snap volume name>/<brick volfile>
The above workaround was used to distinguish between a mount command used
to mount the snapshot volume, and a brick of the snapshot volume, so that
based on what is actually happening, glusterd can return the proper volfile
(client volfile for the former and the brick volfile for the latter). But,
this was causing problems for snapshot restore when brick multiplexing is
enabled. Because, with brick multiplexing, it tries to find the volfile
and sends GETSPEC rpc call to glusterd using the 2nd style of path i.e.
/snaps/<snap name>/<snap volume name>/<brick volfile>
So, when the snapshot brick (which is multiplexed) sends a GETSPEC rpc
request to glusterd for obtaining the brick volume file, glusterd was
returning the client volume file of the snapshot volume instead of the
brick volume file.
