nfs: Export subvolumes on per-subvolume CHILD-UP
..so that nfs clients can mount an UP subvolume even if other subvolumes havent come up yet. This was a problem because nfs was waiting for all children to receive CHILD-UP before exporting any subvolume. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 2093 (volumes cannot start when one node in a replicated setup is down) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2093
