RISC-V: Scalar unaligned access emulated on hotplug CPUs

Browse source

commit 9c528b5f79 upstream.

The check_unaligned_access_emulated() function should have been called
during CPU hotplug to ensure that if all CPUs had emulated unaligned
accesses, the new CPU also does.

This patch adds the call to check_unaligned_access_emulated() in
the hotplug path.
