Don't close process handle provided by WaitForDebugEvent
Only the process handle returned by OpenProcess or CreateProcess needs to
be closed, the one provided by WaitForDebugEvent is closed automatically.
gdbserver/ChangeLog:
2020-05-27 Hannes Domani <ssbssa@yahoo.de>
* win32-low.cc (do_initial_child_stuff): Set open_process_used.
(win32_clear_inferiors): Use open_process_used.
(get_child_debug_event): Likewise.
