media: rkvdec: Disable H.264 error detection

Quite often, the HW get stuck in error condition if a stream error
was detected. As documented, the HW should stop immediately and self
reset. There is likely a problem or a miss-understanding of the self
reset mechanism, as unless we make a long pause, the next command
will then report an error even if there is no error in it.

Disabling error detection fixes the issue, and let the decoder continue
after an error. This patch is safe for backport into older kernels.
