    glusterd: Removing sync lock and unlock inside rcu read critical section
    
    Issue : Glsuterd was crashing during peer probe.
    
    RCA :  In glusterd, we are using big lock which is implemented based on sync
    task frame work for thread synchronization, sync task frame work swap the threads
    if there is no worker pool threads available. Due to this rcu lock and rcu unlock
    was happening  in different threads (urcu-bp will not allow this), resulting into
    glusterd crash.
    
    fix : Removing sync lock and unlock inside rcu read critical section, which was left out by
    http://review.gluster.org/#/c/10285/ patch.
