[NETAPI32]: Fix misusage of a pointer, that caused a crash when using the command "net localgroup". Address one of the problems described in CORE-11081.
Note that those ((ULONG_PTR)the_pointer + sizeof(type_pointed_by_the_pointer)) could be somewhat short cut into: (the_pointer + 1) (with the_pointer being of type *type_pointed_by_the_pointer). But anyway...
