MLK-16536-14 video: fbdev: dcss: correct ret value for 'dcss_wait_for_vsync()'

Browse source 
The correct return value for 'dcss_wait_for_vsync()' when
it executes successfully should be '0'. But this current
value now gets from 'wait_event_interruptible_timeout()'
which returns non-zero value when the wait is not timeout.
