When a remote port becomes ready and a LOGO is received before the READY event is in rport_work waiting on the mutex, the event is changed to LOGO and the work queued, so both the calls to rport_work see the LOGO event, and both try to do the list_del(), causing a crash.
Don't change the event if it is already set.
