[Nouveau] [PATCH 06/38] x86/mmiotrace: Replace deprecated CPU-hotplug functions.

[Sebastian Andrzej Siewior]

The functions get_online_cpus() and put_online_cpus() have been
deprecated during the CPU hotplug rework. They map directly to
cpus_read_lock() and cpus_read_unlock().

Replace deprecated CPU-hotplug functions with the official version.
The behavior remains unchanged.
