[AD] small alsamidi fix

[Elias Pschernig <elias@xxxxxxxxxx>]

Just discovered a small bug in the alsamidi code. The return value of
snd_rawmidi_write is undocumented in the alsa docs.. and apparently, it
is not an error value as the code assumed - at least I can hear the midi
being played by timidity despite the error messages the current code
gave.
