drm/msm/sde: re-init delayed work in sde encoder enable



When multidisplay is enabled, delayed_off_work can be submitted to
different crtc worker thread and violate kernel's rule for delayed
task that work must not be used with >1 worker.

This change will re-initialize the delayed work to allow it submitted
to different worker.
