redo: radix tree test suite: fix compilation
[ This resurrects commit 53855d10f456, which was reverted in
2b41226b39b6. It depended on commit d544abd5ff7d ("lib/radix-tree:
Convert to hotplug state machine") so now it is correct to apply ]
Patch "lib/radix-tree: Convert to hotplug state machine" breaks the test
suite as it adds a call to cpuhp_setup_state_nocalls() which is not
currently emulated in the test suite. Add it, and delete the emulation
of the old CPU hotplug mechanism.
