KVM: Fix the indentation to match coding style

There is a bad indentation in next&queue branch. The patch looks like
fixes nothing though it fixes the indentation.

Before fixing:

                 if (!handle_fastpath_set_x2apic_icr_irqoff(vcpu, data)) {
                         kvm_skip_emulated_instruction(vcpu);
                         ret = EXIT_FASTPATH_EXIT_HANDLED;
                }
                 break;
         case MSR_IA32_TSCDEADLINE:

After fixing:

                 if (!handle_fastpath_set_x2apic_icr_irqoff(vcpu, data)) {
                         kvm_skip_emulated_instruction(vcpu);
                         ret = EXIT_FASTPATH_EXIT_HANDLED;
                 }
                 break;
         case MSR_IA32_TSCDEADLINE:
