[PATCH v2 3/4] rv/reactors: export rv_register_reactor() and rv_unregister_reactor()

[wen.yang@linux.dev]

From: Wen Yang <wen.yang@linux.dev>

rv_react() is exported to modules, but the reactor registration helpers
are not.  Export them with EXPORT_SYMBOL_GPL() so reactor modules and
the tristate KUnit test module can register and unregister reactors
without hitting undefined symbol errors at load time.
