avcodec/nvenc: unregister input resource when unmapping 

Currently the resource is only ever unregistered when the
registered_frames array is fully in use and an unmapped entry is re-used
and cleaned up.
I'm pretty sure the frame will have been cleaned up before that happens,
so I'm kinda surprised this never blew up.
