libmicrohttpd: Fix a segmentation fault on upgrade error
When a connection upgrade is requested and when the
request sent an error reply, it happened most often
that a segmentation fault occured.
The patch applied here is a backport from the
upstream (see https://gnunet.org/git/libmicrohttpd.git/
commit b4216c60fdb5b48f6cfec416301fc63a1167e6cd).
