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().
