[SCSI] libfc: fix rport event race between READY and LOGO

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.
