ACPI: HMAT: preserve hmat_adist_nb notifier block
Remove __meminitdata from hmat_adist_nb declaration preserving it even
when CONFIG_MEMORY_HOTPLUG is not set. Otherwise further notifier
registrations using register_mt_adistance_algorithm() will find a
notifier chain likely corrupted.
This is the case when cxl_region_probe() calls
register_mt_adistance_algorithm() what can happen when CXL regions
are dynamically created at any time from Type3 device(s) or when a Type2
device is initialized at its driver probe.
