drm/ssd130x: Fix possible uninitialized usage of crtc_state variable
Avoid a possible uninitialized use of the crtc_state variable in function
ssd132x_primary_plane_atomic_check() and avoid the following Smatch warn:
drivers/gpu/drm/solomon/ssd130x.c:921 ssd132x_primary_plane_atomic_check()
error: uninitialized symbol 'crtc_state'.
Fixes: fdd591e00a9c ("drm/ssd130x: Add support for the SSD132x OLED controller family")
Reported-by: Dan Carpenter <dan.carpenter@linaro.org>
Closes: https://lore.kernel.org/dri-devel/7dd6ca45-8263-44fe-a318-2fd9d761425d@moroto.mountain/
