drm/rockchip: Don't spam logs in atomic check

Browse Source 
commit 43dae319b50fac075ad864f84501c703ef20eb2b upstream.

Userspace should not be able to trigger DRM_ERROR messages to spam the
logs; especially not through atomic commit parameters which are
completely legitimate for userspace to attempt.
