Kees Cook 2bf8496f6e lkdtm/usercopy: Moves the KERNEL_DS test to non-canonical
The prior implementation of the KERNEL_DS fault checking would work on
any unmapped kernel address, but this was narrowed to the non-canonical
range instead. This adjusts the LKDTM test to match.

Fixes: 00c42373d3 ("x86-64: add warning for non-canonical user access address dereferences")
