Andrey Ryabinin 786a895991 kasan: disable memory hotplug 
Currently memory hotplug won't work with KASan.  As we don't have shadow
for hotplugged memory, kernel will crash on the first access to it.  To
make this work we will need to allocate shadow for new memory.

At some future point proper memory hotplug support will be implemented.
Until then, print a warning at startup and disable memory hot-add.
