[SCSI] zfcp: Remove the useless ZFCP_REQ_AUTO_CLEANUP flag
The flag ZFCP_REQ_AUTO_CLEANUP was useless as the ZFCP_STATUS_FSFREQ_CLEANUP flag is there for exactly the same purpose. Signed-off-by: Swen Schillig <swen@vnet.ibm.com> Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
