tcm_loop: Fixup tag handling
commit 6375f8908255ea7438b60bb5998e6b3e1628500d upstream.
The SCSI command tag is set to the tag assigned from the block
layer, not the SCSI-II tag message. So we need to convert
it into the correct SCSI-II tag message based on the
device flags, not the tag value itself.
