[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.
