[SCSI] Fix erratic device offline during EH
Commit 18a4d0a22ed6c54b67af7718c305cd010f09ddf8 (Handle disk devices which can not process medium access commands) was introduced to offline any device which cannot process medium access commands. However, commit 3eef6257de48ff84a5d98ca533685df8a3beaeb8 (Reduce error recovery time by reducing use of TURs) reduced the number of TURs by sending it only on the first failing command, which might or might not be a medium access command. So in combination this results in an erratic device offlining during EH; if the command where the TUR was sent upon happens to be a medium access command the device will be set offline, if not everything proceeds as normal. This patch moves the check to the final test, eliminating this problem. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
