The host driver is supposed to call mmc_resume_host from it's resume
callback. This should be called before the child's resume callback.

I don't see that - as I say above, the correct sequence is:
- host device resume
- calls mmc_resume_host()
- child's device resume (mmc_blk_resume)
- mmc_queue_resume()
