Subject[PATCH 09/11] bcache: use kmalloc to allocate bio in bch_data_verify()
This function allocates a bio, then a collection
of pages. It copes with failure.

It currently uses a mempool() to allocate the bio,
but alloc_page() to allocate the pages. These fail
in different ways, so the usage is inconsistent.

Change the bio_clone() to bio_clone_kmalloc()
so that no pool is used either for the bio or the pages.
