ALSA: mtpav - Fix initial value for input hwport

Fix the initial value for input hwport. The old value (-1) may cause Oops when an realtime MIDI byte is received before the input port is explicitly given. Instead, now it's set to the broadcasting as default. Tested-by: Holger Dehnhardt <[email protected]> Cc: <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
