Subject: [PATCH] http/fetch: Pass a non-null buffer to
 ne_set_request_body_buffer API

Newer versions of neon has added a check for non-null arguments for
ne_set_request_body_buffer() API and this is triggered but older
compiler only treats -Wnonnull as warning so all was fine, however gcc
12.2 has started to throw this warning as error by default and builds
are breaking

Fixes
src/HTTPFetch.cc:186:38: warning: null passed to a callee that requires a non-null argument [-Wnonnull]
                        ne_set_request_body_buffer(req,0,0);
                                                       ~  ^
