Subject: [PATCH -next] drm/sti: remove set but not used variable 'priv'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/sti/sti_crtc.c: In function 'sti_crtc_vblank_cb':
drivers/gpu/drm/sti/sti_crtc.c:255:22: warning:
 variable 'priv' set but not used [-Wunused-but-set-variable]

It never used since introduction in
  9e1f05b28009 ("drm/sti: rename files and functions")
