VIGS: set proper get_vblank_counter callback

There is no hw frame counter available in vigs hence fallback to the
default implementation provided by drm. The former drm_vblank_count()
was causing a kernel warning in drm_update_vblank_count().

See commit b44f84081b8db1b5830cbd30280ba1109cc1a084 for details.
