[PATCH] s390: zfcp host adapter

zfcp host adapter change:
 - Return -EIO if wait_event_interruptible_timeout was interrupted.
 - Reduce stack uage of zfcp_cfdc_dev_ioctl.
 - Make zfcp_sg_list_[alloc,free] more consistent.
 - Store driver version to zfcp_data structure.
 - Add missing FSF states and make corresponding log messages consistent.
 - Always wait for completion in zfcp_scsi_command_sync.
 - Add Andreas to authors list.
 - Add timeout for cfdc upload/download.
 - Add support for temporary units (units not registered to the scsi stack).
 - Allow sending of ELS commands to ports by their d_id.
 - Increase port refcount while link test is running.
