CRAS: iodev_list - Enable/disable active node for pinned stream

When a pinned stream is connected, the active node on the iodev-
to-pin might not work properly due to it was left in disabled
state when user's last action was switching to the other iodev.
Fix this problem by calling update_active_node() when a pinned
stream connected and removed.
