disp: msm: sde: fix release fence signaling in error cases

Browse Source 
Handle release fence/frame-done error signalling for
error case like esd failure, pp_done timeout, interrupt
disable on cpu, etc. It fixes the race condition for
pending_frame count update and also triggers correct
wait function for wr_ptr wait failure.
