[PATCH 2/2] drm/vmwgfx: Fix uninitialized return in vmw_kms_helper_dirty()

[Christian Engelmayer <cengelma@gmx.at>]

Function vmw_kms_helper_dirty() uses the uninitialized variable ret as
return value. Make the result deterministic and directly return as the
variable is unused anyway. Detected by Coverity CID 1324255.
