disp: msm: sde: allow frame_done count to reach till 2

Browse source 
A frame trigger with posted start may have two frames
in wait state due to irq disable on that CPU. In such
case, frame_done count can reach till 2. Allowing count
only till 1, can cause the release_fence trigger miss
and a buffer is held by DPU driver.
