In rpoc_handle_vdev(), rvdev is not freed properly on the error path and
one of the labels is misnamed. Fix this up.

Fixes: 086d08725d34 ("remoteproc: create vdev subdevice with specific dma memory pool")

Actually, don't apply this. I didn't realise that device_unregister
already frees memory. Sorry for the noise!
