Remove superfluous assignment in add_params.

This fixes the superfluous assignment that Coverity reported in add_params,
and changes the starting index from 0 to num_params - n in order for it to
work properly if add_params is called multiple times.

validate_params calls error so it doesn't matter that we don't check the
results here.  The results is checked in individual parameter updates after
front-end initialization.
