<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">switch-on-port-available: Fix switching away from unplugged headphones

Commits 323195e305 ("switch-on-port-available: Switch to headphones on
unknown availability") and d83ad6990e ("module-alsa-card: Drop
availability groups with only one port") broke switching from headphones
to speakers when headphones are unplugged. switch_from_port() selects
speakers, whose availability is unknown and availability group is unset,
and then calls switch_to_port(). The new logic in switch_on_port()
unintentionally blocked that switch.

This patch moves the problematic logic from switch_to_port() to
port_available_hook_callback() where it doesn't interfere with
switch_from_port().
