qemuMigrationDstPrepareStorage: Reject migration into 'dir' and 'vhost-user' types

Browse Source 
Migrating into a 'directory' won't ever work as we ask qemu to emulate a
fat filesystem, so restoring of the files won't be possible. Same for
'vhost-user' disks which don't support blockjobs as there's no block
backend used in qemu.
