I still get this on 4.4.0-rc7-1.g276c9f4-default. Since this did not
happen on 4.3 I checked the scsi changes and found the following commit:
scsi: restart list search after unlock in scsi_remove_target
Christoph, can it cause this issue?

Apparently yes. Bad hard a patch to avoid this when he resubmitted
my patch, which for some reason didn't get apply. Can you grab it
from the list archives and give it a try?

Do you mean the following patch?
"[PATCH v2] Separate target visibility from reaped state information" [1]
I can give it a try but it will likely take a few days.
