[I/OAT]: Remove CPU hotplug lock from net_dma_rebalance
Remove the lock_cpu_hotplug()/unlock_cpu_hotplug() calls from
net_dma_rebalance
The lock_cpu_hotplug()/unlock_cpu_hotplug() sequence in
net_dma_rebalance is both incorrect (as pointed out by David Miller)
because lock_cpu_hotplug() may sleep while the net_dma_event_lock
spinlock is held, and unnecessary (as pointed out by Andrew Morton) as
spin_lock() disables preemption which protects from CPU hotplug
events.
