Subject: media: mtk-vcodec: Fix an error handling path in 'mtk_vcodec_probe()'
Author:  Christophe JAILLET <[email protected]>
Date:    Thu Nov 11 14:17:51 2021 +0100

In case of error the 'media_device_init()' call is not balanced by a
corresponding 'media_device_cleanup()' call.

Add it, when needed, as already done in the remove function.

Fixes: 118add98f80e ("media: mtk-vcodec: vdec: add media device if using 
stateless api")
