impl-node: correctly synchronize suspend state with remote node

Browse source 
Previously, if a remote node was set to running and immediately reverted
to suspended state, the remote node stayed in running state. This occurred
because suspend_node sent suspend command only when the locally cached
state was "idle" or "running."

Modified to send suspend to a node whenever its pending state is not
"suspended," ensuring the command is sent during state transitions.

Fixes #5026
