addpm.c: Don't pass REG_OPTION_NON_VOLATILE to RegOpenKeyEx

* nt/addpm.c (add_registry): Pass 0 to ulOptions argument of
RegOpenKeyEx, not REG_OPTION_NON_VOLATILE.  This doesn't change
current behavior because REG_OPTION_NON_VOLATILE is defined to
be 0L anyway, but that option is actually documented only for
RegCreateKeyEx.
