Sean Christopherson 73b8dc0413 KVM: Teardown VFIO ops earlier in kvm_exit() 
Move the call to kvm_vfio_ops_exit() further up kvm_exit() to try and
bring some amount of symmetry to the setup order in kvm_init(), and more
importantly so that the arch hooks are invoked dead last by kvm_exit().
This will allow arch code to move away from the arch hooks without any
change in ordering between arch code and common code in kvm_exit().

That kvm_vfio_ops_exit() is called last appears to be 100% arbitrary.  It
was bolted on after the fact by commit 571ee1b685 ("kvm: vfio: fix
unregister kvm_device_ops of vfio").  The nullified kvm_device_ops_table
is also local to kvm_main.c and is used only when there are active VMs,
so unless arch code is doing something truly bizarre, nullifying the
table earlier in kvm_exit() is little more than a nop.
