drm: rcar-du: Fix the return value in case of error in 'rcar_du_crtc_set_crc_source()'

Browse Source 
We return 0 unconditionally in 'rcar_du_crtc_set_crc_source()'.
However, 'ret' is set to some error codes if some function calls fail.

Return 'ret' instead to propagate the error code.

Fixes: 47a52d024e ("media: drm: rcar-du: Add support for CRC computation")
