[media] media/rc: fix oops on unloading module rc-core
During modiles initialization rc-core schedules work which calls request_module() several times to load ir-*-decoder modules, but it does not wait or cancel this work on module unloading. rc-core should use request_module_nowait() instead, because it anyway cannot load modules synchronously or cancel/wait pending work on unloading, because this leads to deadlock on modules_mutex between several "modprobe" processes.
