[PATCH] Add missing check for r->cache pointer validity in ngx_http_upstream_send_response()

In ngx_http_upstream_send_response() function there are a lot of
checks for r->cache pointer validity.
But it is absent for if (u->cacheable){}, which starts with dereferencing
    valid = r->cache->valid_sec;
straight away.

If this considered to be an issue - patch attempting to fix it is attached.

Best wishes,
