[PATCH-v2 0/3] KVM: Take missing slots_lock for

This patchset consists of three patches:

  [1/3] KVM: Take missing slots_lock for kvm_io_bus_unregister_dev()
  [2/3] KVM: Centralize slots_lock aquisition during KVM_CREATE_IRQCHIP
  [3/3] KVM: Centralize irq_lock aquisition during KVM_CREATE_IRQCHIP

Though patch 1 is a fix, this is only for an error handling path.
Patches 2,3 are just for coding style consistency. So pick up those
whitch match your policy.


Changelog:
  moved slots_lock and irq_lock aquisition to their caller following
  Marcelo's advice.

Thanks,
  Takuya
