[PATCH 5.16 0191/1039] media: mtk-vcodec: Fix an error handling path in mtk_vcodec_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 615c6f28b9ad7efc9bfbef2cafc6a0c5bc0c21e0 ]

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")
