Upstream: disabled upgrading in subrequests.

Upgrading an upstream connection is usually followed by reading from the client
which a subrequest is not allowed to do.  Moreover, accessing the header_in
request field while processing upgraded connection ends up with a null pointer
dereference since the header_in buffer is only created for the the main request.
