proxy: update comment on mutex for removeRedirect()
proxy: update comment on mutex for removeRedirect()

Update the comment for removeRedirect(): Since commit d65adf83f8be
("bpf: Use iptables TPROXY and shared proxy listeners"), this is not
p.mutex but proxyPortsMutex which is used in the returned finalize
function.
