[SCSI] zfcp: fix bug during adapter shutdown
Fixes a race between zfcp_fsf_req_dismiss_all and
zfcp_qdio_reqid_check. During adapter shutdown it occurred that a
request was cleaned up twice. First during its normal
completion. Second when dismiss_all was called. The fix is to
serialize access to fsf request list between zfcp_fsf_req_dismiss_all
and zfcp_qdio_reqid_check and delete a fsf request from the list if
its completion is triggered. (Additionally a rwlock was replaced by a
spinlock and fsf_req_cleanup was eliminated.)
