In the v4.4 cycle, we relaxed the requirement for assigning mtd->owner, but we
didn't remove this error case. It's hit only by drivers that are both:
(a) using nand_scan() directly and
(b) built as modules
We haven't seen explicit complaints about this (most use cases don't fit one or
both of the above), but we should definitely not be BUG()'ing here.
