I am pretty sure this has to be done anyway, no matter why the
xmit_task callback failed
Even if we abort? this just follows the same logic as
iscsi_prep_scsi_cmd_pdu error flow.
yes, take a 2nd look on iscsi_prep_scsi_cmd_pdu and you'll see that
all the possible error cases take place **before** session->cmdsn is
incremented
Ahhh, yes... So dec the cmdsn regardless.
