rv: Propagate rv_register_reactor() error from reactor init

Both register_react_printk() and register_react_panic() ignore the
return value of rv_register_reactor() and always return 0.  If the
registration fails (e.g. a duplicate reactor name), the init functions
silently report success even though the reactor was not registered.

Propagate the error from rv_register_reactor() so a failed registration
is reported instead of being silently ignored.
