rmtfs: Exit even though there's no rprocfd

Browse Source 
Attempting to shut down a system with rmtfs running without an
associated remoteproc results in systemd waiting forever for the
remoteproc code to never signal that it's done.

Instead exit immediately when signalled, when there's no associated
remoteproc.
