Commit d98f26073beb ("target/i386: kvm: add VMX migration blocker")
added migration blocker for vCPU exposed with Intel VMX because QEMU
doesn't yet contain code to support migration of nested virtualization
workloads.

However, that commit missed adding deletion of the migration blocker in
case init of vCPU failed. Similar to invtsc_mig_blocker. This commit fix
that issue.
