target/i386: Fix VM migration when interrupt based APF is enabled
VM with interrupt based APF enabled fails to migrate:
qemu-system-x86_64: error: failed to set MSR 0x4b564d02 to 0xf3
We have two issues:
1) There is a typo in kvm_put_msrs() and we write async_pf_int_msr
to MSR_KVM_ASYNC_PF_EN (instead of MSR_KVM_ASYNC_PF_INT)
2) We restore MSR_KVM_ASYNC_PF_EN before MSR_KVM_ASYNC_PF_INT is set
and this violates the check in KVM.
Re-order MSR_KVM_ASYNC_PF_EN/MSR_KVM_ASYNC_PF_INT setting (and
kvm_get_msrs() for consistency) and fix the typo.
