Morph DONE result from a sub-request handler to OK as DONE is only relevant

when we are the main request.

This fixes a problem with mod_include printing out an error message on DAV
sub-requests because mod_dav will return DONE instead of OK.  This would
result in the correct output merged in with an error string.
