media: mtk-vcodec: Fix an error handling path in 'asid_allocator_init()'
Commit Message
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")
