Subject: [PATCH 2/5] rpmsg: core: Fix incorrect return value documentation

The unregister_rpmsg_driver() function has a void return type but the
documentation incorrectly described a return value. Remove the incorrect
return value documentation to match the actual function signature.

Fixes: bcabbccabffe ("rpmsg: add virtio-based remote processor messaging bus")
