End a request quietly when the client has gone

A write that failed with EPIPE on an uncached page died into an error
page, which died again at exit when the page could not be sent either,
and git logged a recursion warning on every dropped connection. A
filter that exits early fails a write the same way, so the quiet exit
is kept for writes that reach the client itself.
