Steffen Maier 44f747fff6 [SCSI] zfcp: return early from slave_destroy if slave_alloc returned early ... zfcp_scsi_slave_destroy erroneously always tried to finish its task even if the corresponding previous zfcp_scsi_slave_alloc returned early. This can lead to kernel page faults on accessing uninitialized fields of struct zfcp_scsi_dev in zfcp_erp_lun_shutdown_wait. Take the port field of the struct to determine if slave_alloc returned early. This zfcp bug is exposed by 4e6c82b (in turn fixing f7c9c6b to be compatible with 21208ae) which can call slave_destroy for a corresponding previous slave_alloc that did not finish. This patch is based on James Bottomley's fix suggestion in http://www.spinics.net/lists/linux-scsi/msg55449.html.
