disp: msm: sde: allow delayed_off_work scheduling always

Add changes to allow delayed_off_work scheduling in all cases.
Skip scheduling only in panel_dead cases where delay_kickoff
is enabled. This will fix the issue seen with commit 08d04c2f
("disp: msm: sde: avoid rc restart when triggered from panel dead").
