Move MIDI filters imprecise handling from 2nd pass to 1st

This doesn't change the policy since configurations are given an
additional 1000 penalty if audio_in != possible_in, and will thus be
trumped by any "precise" configuration (unless the latter has 1000
excess or missing outputs which should be less than likely).
