ALSA: portman2x4: Check card index validity at probe

Although portman2x4 driver has a check of the given devptr->id value,
it doesn't check for a negative id, which is often given as "none" or
such value when bound via sysfs.  This may lead to OOB access for
index[] and other parameters.

Add a sanity check for the card index and warn/correct it if it's a
value out of the range.
