[PATCH 4/4] virsh: doMigrate: Require --copy-storage-(all|inc) with --migrate-disks

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Users need to enable non-shared-storage migration, otherwise the disks
specified via '--migrate-disks' will be ignored.

Add an error message to inform the users of their wrong config.
