impl-node: improve suspend

Browse source 
Make sure we can only suspend when the node is (going to) IDLE. We don't
really want to allow applications to suspend a node that is running or
starting up.

This might fix a race when a node is suspended at the same time it is
started and cause silence. It also fixes the issue of total silence when
doing "pactl suspend <node> 1" on a running node.

See #3378
