KVM: fix cleanup_srcu_struct on vm destruction
cleanup_srcu_struct on VM destruction remains broken:
BUG: unable to handle kernel paging request at ffffffffffffffff
IP: [<ffffffff802533d2>] srcu_read_lock+0x16/0x21
RIP: 0010:[<ffffffff802533d2>] [<ffffffff802533d2>] srcu_read_lock+0x16/0x21
Call Trace:
[<ffffffffa05354c4>] kvm_arch_vcpu_uninit+0x1b/0x48 [kvm]
[<ffffffffa05339c6>] kvm_vcpu_uninit+0x9/0x15 [kvm]
[<ffffffffa0569f7d>] vmx_free_vcpu+0x7f/0x8f [kvm_intel]
[<ffffffffa05357b5>] kvm_arch_destroy_vm+0x78/0x111 [kvm]
[<ffffffffa053315b>] kvm_put_kvm+0xd4/0xfe [kvm]
Move it to kvm_arch_destroy_vm.
