[PATCH] parameter: fix parameter name to reflect usage

[Ahmad Fatoum]

Everywhere the max parameter is used, it's assumed it has the value of
the highest index into the names array + 1. As counting begins from
zero, rename it to num_names in the prototypes for clarity.

This is already the name used internally in struct param_d.

No functional change.
