   Noticed this while updating the CNode fuzzing in #20210.

   • cc26fab48d76a813d798657b18ae1af08a301150 created test/fuzz/net.cpp in May 2020

   • 79ef8324d4c85ed16a304e98805724b8a created a CNode factory utility test/fuzz/util.h::ConsumeNode() in October 2020

   This PR updates fuzz/net.cpp from the first commit to use ConsumeNode() from the second commit.
