description:
Sub filter: restored ngx_http_set_ctx() at the proper place.
Previously, ngx_http_sub_header_filter() could fail with a partially
initialized context, later accessed in ngx_http_sub_body_filter()
if called from the perl content handler.
The issue had appeared in 2c045e5b8291 (1.9.4).
A better fix would be to handle ngx_http_send_header() errors in
the perl module, though this doesn't seem to be easy enough.
