kasan: fix memory hotplug during boot
commit 3f1959721558a976aaf9c2024d5bc884e6411bf7 upstream.
Using module_init() is wrong. E.g. ACPI adds and onlines memory before
our memory notifier gets registered.
This makes sure that ACPI memory detected during boot up will not result
in a kernel crash.
Easily reproducible with QEMU, just specify a DIMM when starting up.
