Fixed ngx_http_test_reading() to finalize request properly.

Previous code called ngx_http_finalize_request() with rc = 0.  This is
ok if a response status was already set, but resulted in "000" being
logged if it wasn't.  In particular this happened with limit_req
if a connection was prematurely closed during limit_req delay.
