winecoreaudio: Switch midi_in_lock() away from a syscall prototype.

Going to the previous commit fixes the issue. When testing, sometimes it would
play a few seconds of audio before completely refusing to play any audio
whatsoever. The audio does play consistently on the commit before the
aforementioned commit, so I'm pretty certain this is the correct commit.
