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 suspend a node that is running or starting up.

Deactivate the node while we suspend so that graph recalc because of the
unprepared links will not try to prepare the links again.

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.
