drm/i915: correct the input parameter on _intel_dsb_commit() 

Current, the dewake_scanline variable is defined as unsigned int,
an unsigned int variable that is always greater than or equal to 0.
when _intel_dsb_commit function is called by intel_dsb_commit function,
the dewake_scanline variable may have an int value.
So the dewake_scanline variable is necessary to defined as an int.
