sna: Inject a batch flush before adding a fresh bo

Fresh bo (those without a reservation already defined, ala
presumed_offset) will cause the kernel to do a full relocation pass. So,
if possible flush the already correct batch in the hope of trimming the
amount of checking the kernel has to perform on this new batch.
