[PATCH AUTOSEL 5.7 012/274] media: vicodec: Fix error codes in probe function

From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit f36592e7b343d853edf44d3545bb68961c0949a4 ]

If these functions fail then we return success, but we should instead
preserve negative error code and return that.

Fixes: fde649b418d1 ("media: vicodec: Register another node for stateless decoder")
Fixes: c022a4a95722 ("media: vicodec: add struct for encoder/decoder instance")
