    [NTOS:IO] OpenRegistryHandlesFromSymbolicLink: Use REG_OPTION_NON_VOLATILE
    Use REG_OPTION_NON_VOLATILE instead of REG_OPTION_VOLATILE in all ZwCreateKey calls of
OpenRegistryHandlesFromSymbolicLink, since the keys created/opened by this function,
should be non-volatile (in other words, be saved after reboot).
    Also Device Parameters subkey that is created in IoOpenDeviceInterfaceRegistryKey
(which uses that routine as well), is non-volatile too, so the parent keys whose contain
it, cannot be volatile.
    It will fix an error with status 0xc0000181 (STATUS_CHILD_MUST_BE_VOLATILE) occuring
during loading kernel mode audio drivers from Windows XP/2003, especially checked (debug)
versions, with my IoGetDeviceInterfaceAlias implementation. Also it may fix other error
cases.
