media: venus: Fix probe error handling

Browse Source 
commit 523cea3a19f0b3b020a4745344c136a636e6ffd7 upstream.

Video device registering has been moved earlier in the probe function,
but the new order has not been propagated to error handling. This means
we can end with unreleased resources on error (e.g dangling video device
on missing firmware probe aborting).

Fixes: 08b1cf474b ("media: venus: core, venc, vdec: Fix probe dependency error")
