Michael S. Tsirkin c8ce057eaf KVM: improve comment on rcu use in irqfd_deassign 
The RCU use in kvm_irqfd_deassign is tricky: we have rcu_assign_pointer
but no synchronize_rcu: synchronize_rcu is done by kvm_irq_routing_update
which we share a spinlock with.

Fix up a comment in an attempt to make this clearer.
