T5837: cleanup use of calls to vyos.configdict.node_changed()

node_changed() will return a list of changed keys under "path". We are not
always interested what changed, sometimes we are only interested if something
changed at all, that what vyos.configdict.is_node_changed() is for.

(cherry picked from commit 5e7a8288d06a6d6beee5e1abd2e06698ab778650)
