HTTP/2: fixed null pointer dereference with server push.

r->headers_in.host can be NULL in ngx_http_v2_push_resource().

This happens when a request is terminated with 400 before the :authority
or Host header is parsed, and either pushing is enabled on the server{}
level or error_page 400 redirects to a location with pushes configured.
