[libvirt] [PATCH v2] qemu: Properly label FDs when restoring domain with static label

[Shivaprasad G Bhat]

The restore of a saved image file fails when the selinux context is static.
The libvirt has to set the conext of save image file handle to that of
the guest before handing off the FD to qemu.
