Ⅰ. Describe what this PR does
when client close the connection in advance, reserveproxy.ServeHTTP will panic, and everything after ServeHTTP will be skipped except "defer". so the element in reqChan(function WithMaxInFlightLimit) leaks.
reproduce:
curl '127.0.0.1:10261/apis/node.k8s.io/v1beta1/runtimeclasses?resourceVersion=1235193475&timeout=5m&timeoutSeconds=300&watch=true' -o /dev/null -v）MaxRequestInFlight)this pr moves the operation of the chan into defer, to make sure it will run after ServeHTTP
