The crazy bcache bios striking back once again.  I really think it's
harmful having a _MAX value and then having a minor driver
reinterpreting it and sending larger ones.  Until we can lift the
maximum limit in general nad have common code exercise it we really need
to stop bcache from sending these instead of littering the tree with
workarounds.
