w32: Don't use CloseHandle on an arbitrary integer.

* src/assuan-support.c (my_waitpid): Do not close the PID = it is not
a handle.
--

At some time in the distant past we might have used the process object
as pid which obviously required a close.  However this was changed and
so what we did here was to close an arbitrary handle (one which
matches the pid).
