[PATCH 2/4] qemuMigrationSrcBeginPhase: Require storage migration when 'migrate_disks' parameter is specified
If a user passes a list of disks to migrate but don't actually use
'VIR_MIGRATE_NON_SHARED_DISK' or 'VIR_MIGRATE_NON_SHARED_INC' flags the
parameter would be simply ignored without informing the user of the
error.
Add a proper error in such case.
