[SCSI] fix duplicate removal on error path in scsi_sysfs_add_sdev
This patch (as1335) fixes a bug in scsi_sysfs_add_sdev(). Its callers always remove the device if anything goes wrong, so it should never remove the device. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
