4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: James Hogan <james.ho...@imgtec.com> commit 585bb8f9a5e592f2ce7abbe5ed3112d5438d2754 upstream. If either of the memory allocations in kvm_arch_vcpu_create() fail, the vcpu which has been allocated and kvm_vcpu_init'd doesn't get uninit'd in the error handling path. Add a call to kvm_vcpu_uninit() to fix this.
