[SCSI] zfcp: clear adapter failed flag if an fsf request times out.

Browse source 
Must clear adapter failed flag if an fsf request times out. This is
necessary because on link down situations the failed flags gets set
but the QDIO queues are still up. Since an adapter reopen will be
skipped if the failed flag is set an adapter_reopen that is issued
on fsf request timeout has no effect if the local link is down.
Might lead to locked up system if the SCSI stack is waiting for abort
completion.
