drm/omap: Remove set but not used variable 'plane'

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

drivers/gpu/drm/omapdrm/omap_fb.c: In function omap_framebuffer_update_scanout:
drivers/gpu/drm/omapdrm/omap_fb.c:130:16: warning: variable plane set but not used [-Wunused-but-set-variable]

It is not used since commit 2ecceeb53b19 ("drm/omap:
Move buffer pitch/offset to drm_framebuffer")
