Takashi Iwai 2c71ab5270 ALSA: seq: ump: Skip useless ports for static blocks
commit 3bfd7c0ba1 upstream.

When the UMP Endpoint is configured with static blocks, the block
configuration will never change, hence the unused ports will be
unchanged as well.  Creating sequencer ports for those unused ports
is simply useless, and it might be rather confusing for users.
The idea behind the inactive ports was for allowing connections
from/to ports that can become usable later, but this will never
happen for inactive groups in static blocks.

Let's change the sequencer UMP binding to skip those unused ports when
the UMP EP is with static blocks.
