[windows] os::pd_map_memory error detection broken

      Description

        os::pd_map_memory() uses CreateFile to open the file-to-be-mapped, but uses NULL instead of INVALID_HANDLE_VALUE to check if opening the file failed or not.

        Which is wrong, NULL is actually a valid value.

        INVALID_HANDLE_VALUE is -1.

        Seems to be a very old bug; it is in all releases AFAICS.
