[libvirt] [PATCH] qemu: Split shmem preparation as it's supposed to be

[Martin Kletzander]

Since the introduction of shmem, there was a split of preparation code
from the formatting code from qemuBuildCommandLine() into
qemuProcessPrepareDomain().  Let's fix shmem in this regard, so that
we can slowly get to a cleaner codebase.
