disp: msm: sde: avoid encoder power-collapse with pending frames

The encoder idle work is scheduled during the frame-done event
to be executed after a timeout. During the execution, the check
for any on-going/pending frames is invalid as it checks for > 1.
Fix it to check for any non-zero frame-pending and avoid
power-collapse.
