Don't lose pointer to first nonempty buf in ngx_*_sendfile_chain(). In ngx_*_sendfile_chain() when calculating pointer to a first non-zero sized buf, use "in" as iterator. This fixes processing of zero sized buf(s) after EINTR. Otherwise function can return zero sized buf to caller, and later ngx_http_write_filter() logs warning.
