SPDY: fixed segfault with "client_body_in_file_only" enabled. It is possible to send FLAG_FIN in additional empty data frame, even if it is known from the content-length header that request body is empty. And Firefox actually behaves like this (see ticket #357). To simplify code we sacrificed our microoptimization that did not work right due to missing check in the ngx_http_spdy_state_data() function for rb->buf set to NULL.
