When a migration with non-shared storage is started with
VIR_MIGRATE_PARAM_BANDWIDTH set, it will be applied to both memory
migration and each block job started for storage migration. Once the
migration is running virDomainMigrateSetMaxSpeed may be used to change
the bandwidth used by memory migration, but there was no way of changing
storage migration speed. Let's allow virDomainBlockJobSetSpeed during
migration to enable the missing functionality.
