Subject: 4.4.10 lio (iscsi_trx) messages in dmesg

I'm seeing the following message when using the lio iscsi target.  This
message is on the machine with the target.  I have 1 target with 3 luns. 
The luns are /dev/sr0 1 and 2 using pscsi backend.  On the initiator, I
issue eject srX for each of the 3 drives and see this message.  (NOTE: The
initiator's kernel is 3.12.52 and doesn't show any messages)
