glusterd: allow shared-storage to use bricks under glusterd working directory

With commit 44e4db, we are not allowing user to create a volume
using glusterd's working directory as a brick or any sub directory
under glusterd's working directory as a brick.This has broken
shared-storage since the volume "gluster-shared-storage" is
created using the bricks under glusterd's working directory.

With this patch, we let the "gluster-shared-storage" volume
to use bricks under glusterd's working directory.
