----------------
In my understanding of the spec.
`map(tofrom:x[0:256])` only maps the memory segment that x points to. x itself
as a pointer scalar is not mapped.
use_device_addr(x) should fail to find the map of x scalar.
5.2 spec.
If the list item is not a mapped list item, it is assumed to be accessible on
the target device.
To me, it seems just keep &x as it was, in this case &x remains a host address.
But in your patch description, it seems treating x differently from a scalar.
I also applied your patch on main and got segfault because the x has a value of
device address and x[0] fails. This should be the behavior of use_device_ptr
instead of use_device_addr.
