glusterd: Use GF_ATOMIC to update 'blockers' counter at glusterd_conf
Problem:
Currently in glusterd code uses sync_lock/sync_unlock to update blockers
counter which could add delays to the overall transaction phase
escpecially when there's a batch of volume stop operations processed by
glusterd in brick multiplexing mode.
Solution: Use GF_ATOMIC to update blocker counter to ensure unnecessary
context switching can be avoided.
