lib/test_lockup: fix kernel pointer check for separate address spaces
test_kernel_ptr() uses access_ok() to figure out if a given address
points to user space instead of kernel space. However on architectures
that set CONFIG_ALTERNATE_USER_ADDRESS_SPACE, a pointer can be valid
for both, and the check always fails because access_ok() returns true.
Make the check for user space pointers conditional on the type of
address space layout.
