shd/glusterd: Serialize shd manager to prevent race condition
At the time of a glusterd restart, while doing a handshake there is a possibility that multiple shd manager might get executed. Because of this, there is a chance that multiple shd get spawned during a glusterd restart Change-Id: Ie20798441e07d7d7a93b7d38dfb924cea178a920 fixes: bz#1707081 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
