[PATCH 06/13] virDomainSnapshotAlignDisks: Rename 'def' -> 'snapdef'



While this function resides in the snapshot config module the 'def'
variable is referencing the VM definition in most places. Change the
name to 'snapdef' to avoid ambiguity especially since we are also
dealing with the domain definition in this function.
