ALSA: seq: Notify client and port info changes
It was supposed to be notified when a sequencer client info and a port
info has changed (via SNDRV_SEQ_EVENT_CLIENT_CHANGE and
SNDRV_SEQ_EVENT_PORT_CHANGE event, respectively), and there are
already helper functions. But those aren't really sent from the
driver so far, except for the recent support of UMP, simply due to the
lack of implementations.
This patch adds the missing notifications at updating the client and
the port info. The formerly added notification for UMP is dropped
because it's handled now in the port info side.
