    cluster/ec: Handle race between unlock-timer, new lock

    New lock could come at the time timer is on the way to unlock. This was
    to crash in timer thread because thread executing new lock can free up the
    timer_link->fop and then timer thread will try to access structures already

    If the timer event is fired, set lock->release to true and wait for unlock

    Thanks to Xavi and Bhaskar for helping in confirming that this race is the
    Thanks to Kritika for pointing out and explaining how Avati's patch can be
    to fix this bug.
