jack: use configured node.latency when inactive

Browse source 
In the inactive state, use the configured latency values for the
node instead of the current values used in the graph. We need to
do this because the graph only changes the buffer-size to our
requirements when the node becomes active.

Some clients do get_buffer_size before activating and would then
get a different value from when they would activate, causing some
apps to be confused and stop.

See #886
