sonivox: prevent rejection of good but large MIDI files

A security patch that was trying to detect infinite loops
was accidentally rejecting very large MIDI files.
This is because there is a scanning pass that looks at the entire
file. That was generating a very high eventCount.
With this change, we do not check event counts during the scanning pass.
