[PATCH] media: mediatek: vcodec: Fix an error handling path in vdec_msg_queue_init()

[Christophe JAILLET]

All errors go to the error handling path, except this one. Be consistent
and also branch to it.

Fixes: 2f5d0aef37c6 ("media: mediatek: vcodec: support stateless AV1 decoder")

Hi Dan,

your patch is better than mine.
Less verbose and more complete.

Hi Christophe,

This no longer applies after some major rework of the driver from Yunfei that
was merged to our media_stage tree.

Can you rebase this patch (if it is even still relevant)?

Thanks,
