From: Roland Dreier <roland@xxxxxxxxxxxxxxx>
We don't need to change the sign of our prm->residual field; the target
core sets a flag to distinguish overflow and underflow, but
se_cmd->residual_count is always positive. The existing code seems to
be a carryover from the port from scst, which uses the sign of the
residual field to distinguish overflow and underflow.
