Both the winfo variable and the updated copyfd_io() function were introduced in upstream commit ca7ae8916043 ("selftests: mptcp: mptfo Initiator/Listener"), which is not present in v6.1.y. The goal of the backport is to stop on errors from copyfd_io. Therefore, the backport does not depend on the changes in upstream commit ca7ae8916043 ("selftests: mptcp: mptfo Initiator/Listener"). This commit simply removes ', &winfo' to fix a build failure.
