cxl: Adjust extended linear cache failure emission in cxl_acpi

Browse source

The cxl_acpi module spams "Extended linear cache calculation failed"
when the hmat memory target is not found for a node. This is normal
when the memory target does not contain extended linear cache
attributes. Adjust cxl_acpi_set_cache_size() to just return 0 if error
is returned from hmat_get_extended_linear_cache_size(). That is the
only error returned from hmat_get_extended_linear_cache_size() as
-ENOENT.

Also remove the check for -EOPNOTSUPP in cxl_setup_extended_linear_cache()
since that errno is never returned by cxl_acpi_set_cache_size().
