http: get fd from be layer during connection reset

Since it can be non -1, and we must close it, otherwise we will have problems.

And after this patch the following tests report fd 2307 instead of 2309 fd leaks:
$ valgrind --leak-check=full --show-reachable=yes --track-fds=yes --error-exitcode=1 regress --no-fork http/cancel..
==10853== FILE DESCRIPTORS: 2307 open at exit.
