msm_fb: display: increase timeout value to 2 vsync
wait_for_completion_timeout() may timeout before
overlay1_done interrupt when one vsync timeout is specified.
This cause mdp4_overlay_dtv_ wait4_ov_done() to return prematurely
which causes a falsely increased FPS. This patch increases the timeout
value to 2 vsync to prevent premature timeout.
