disp: msm: sde: add changes to fix the sde fence signaled logic

Browse source 
This change allows signalling of sde fences when sequence number is
less than done_count. In current scenario, fence is not signaled as
the subtraction result is not typecasted to int before updating
the status causing the UI thread to block on sde fence.
