This isn't correct (in both meanings: it doesn't correctly remove
headers from subrequest and not a correct way to prevent body from
being read before subrequest).

I would recommend adding fake body to subrequest instead, see
example here:

http://mdounin.ru/hg/ngx_http_auth_request_module/file/a29d74804ff1/ngx_http_auth_request_module.c#l193

Note that it may be also needed to instruct backend to not expect
body, i.e. if you proxy_pass such subrequest you should either use

proxy_pass_request_headers off;

or

proxy_set_header Content-Length "";
