Reverting your patch won't fix the problem because scsi_put_command() will then relinquish the last reference to the device and trigger the same warning. Additionally, blk_run_queue now stands a good chance of running on a freed queue which could trigger a panic. The problem seems to be that device_del() is apparently requiring user context, if that's true, this will bite us not only here, but all over the place ... in fact the fix might have to be to do the target reap through a workqueue. Regardless, your patch isn't the culprit here, it's just the thing which is doing the last put.
