Good point, thanks !

Yes, I need to remove this direct kfree as well, and indeed just let
rpmsg_release_device do its thing when the last reference is dropped.
I should also remove the direct kfree when device_register fails: in
that case, I need only to put_device and let the release handler do
its thing too.

We need that extra put_device in rpmsg_destroy_channel because
device_find_child() is doing get_device before returning it.
Thanks, Grant!
