w32: Fix use of assuan_sendfd.

* kbx/kbx-client-util.c (prepare_data_pipe): Use _get_osfhandle
for pipe to be used for sentfd.
[HAVE_W32_SYSTEM] (datastream_thread): Add the case of NREAD==0.
* tools/gpg-connect-agent.c (do_sendfd): Use es_syshd instead
of es_fileno.
[HAVE_W32_SYSTEM] (do_open): Use %p for formating HANDLE.
