drm/qxl: Fix qxl_noop_get_vblank_counter()
This breaks under the vblank timestamp cleanup patch by Daniel Vetter. Also it is pointless to return anything but zero (or any other constant) if the function doesn't actually query a hw vblank counter. The bogus return of the current drm vblank counter via direct readout or via drm_vblank_count() is found in many of the new kms drivers, but it does exactly nothing different from returning any arbitrary constant - it's a no operation. Let's simply return 0 - Easy and fast. Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Cc: Dave Airlie <airlied@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
