qemu: migration: Unlock vm on failed ACL check in protocol v2 APIs

Avoid leaving the domain locked on a failed ACL check in
qemuDomainMigratePerform() and qemuDomainMigrateFinish2().

Introduced in commit abf75aea247e (Add ACL checks into the QEMU driver).

(cherry picked from commit 2bdcd29c713dfedd813c89f56ae98f6f3898313d)
