Fix Mixer Store/Recall

Two main problems are addressed by this commit.

First, storage of
parameters was broken because the index for values was set by the
parameter count, not the control port count which set_processor_param()
expects.

Second, the value was not clamped to pd.upper and pd.lower causing some
parameters to fail when set.

This invalidates previous mixer store files.
