[glusterd/snapshot] Glusterd crashes when a same command
eg snapshot create is fired simultaneously on a node Cause: In glusterd_mgmt_v3_initiate_snap_phases() , the function glusterd_mgmt_v3_post_validate() asserts on the NULL value of req_dic. req_dic is not initialized as glusterd_mgmt_v3_initiate_lockdown() is not able to acquire the lock and comes to the "out" section, before initializing req_dic (via glusterd_mgmt_v3_build_payload) Fix: Call glusterd_mgmt_v3_post_validate() only if the lock is acquired.
