rpmsg: glink: Fix rpmsg_register_device err handling
The device release function is set before registering with rpmsg. If
rpmsg registration fails, the framework will call device_put(), which
invokes the release function. The channel create logic does not need to
free rpdev if rpmsg_register_device() fails and release is called.
