Rob Bradford 7be69edf51 hypervisor: kvm: Introduce Mutex around VcpuFd ...

This is required as the VcpuFd::run and VcpuFd::set_immediate_exit
methods now take a &mut self. I explored alternative solutions:

1. Using RefCell for runtime interior mutability - the Vcpu trait is
   Sync and it's not possible to use RefCell with types that are Sync.
2. Using UnsafeCell - the mutable reference nature of ::run and and
   ::set_kvm_immediate_exit was added for a reason so it unwise to
   bypass this.
3. Adjusting the trait interface to expose the &mut self - this requires
   an Arc<Mutex<>> around the hypervisor::vcpu::Vcpu object and was very
   intrusive.
