[libvirt] [PATCH] qemuMigrationIsAllowed: Forbid migration of rebooting domain

[Michal Privoznik]

https://bugzilla.redhat.com/show_bug.cgi?id=744967

If a domain is rebooting and a migrate API is called meanwhile we would
have to transfer the fakeReboot attribute to the destination in order to
prevent domain doing plain shutdown over there. What about forbidding
this silly corner case instead? Same goes for saving a domain to a file.
