drm: omapdrm: if omap_plane_atomic_update fails, disable plane
omap_plane_atomic_update() calls dispc_ovl_setup(), which can fail (but
shouldn't). To make the code a bit more robust, make sure the plane gets
disabled if dispc_ovl_setup() fails, as otherwise we might get illegal
HW configuration leading to error interrupts.
