rc-core: race condition during ir_raw_event_register()

commit 963761a0b2e85663ee4a5630f72930885a06598a upstream.

A rc device can call ir_raw_event_handle() after rc_allocate_device(),
but before rc_register_device() has completed. This is racey because
rcdev->raw is set before rcdev->raw->thread has a valid value.
