[libvirt] [PATCH 11/12] qemu: Simplify allowing access to storage file for block copy

[Peter Krempa]

One code path open-coded qemuDomainStorageSourceChainAccessAllow badly
and also did not integrate with the locking code.

Replace the separate calls with qemuDomainStorageSourceChainAccessAllow
which does everything internally.
