[SCSI] zfcp: fix compile warning
Get rid of this one: drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_thread': drivers/s390/scsi/zfcp_erp.c:1400: warning: ignoring return value of 'down_interruptible', declared with attribute warn_unused_result zfcp_erp_thread is a kernel thread which can't receive any signals. So introduce a dummy variable and get rid of the warning.
