disp: msm: sde: trigger esd recovery before event notification

ESD recovery schedules KICKOFF event on event_thread,
switches the vsync source to wd_timer and waits for
pending frame. This work is triggered from workthread
and it must be finished before panel dead event
notification to avoid race condition with power off
sequence. This change also cancels the delayed work
after encoder is disabled.
