MIPS: KVM: Fix memory leak on VCPU
commit 8c9eb041cf76038eb3b62ee259607eec9b89f48d upstream. kvm_arch_vcpu_free() is called in 2 code paths: 1) kvm_vm_ioctl() kvm_vm_ioctl_create_vcpu() kvm_arch_vcpu_destroy() kvm_arch_vcpu_free() 2) kvm_put_kvm() kvm_destroy_vm() kvm_arch_destroy_vm() kvm_mips_free_vcpus() kvm_arch_vcpu_free() Neither of the paths handles VCPU free. We need to do it in kvm_arch_vcpu_free() corresponding to the memory allocation in kvm_arch_vcpu_create().
