ALSA: hdspm - Fix midi port initialization

Depending on the model and the presence of a TCO module, the number of
midi ports varies. Some have 1 port (MADIface), some have 2 (default),
with TCO, there are 3.

Don't hardcode the number of midi ports to initialize.

This patch also fixes a boot lockup on MADIface.
