md: use bio_kmalloc rather than bio_alloc when failure is acceptable.
bio_alloc can never fail (as it uses a mempool) but an block
indefinitely, especially if the caller is holding a reference to a
previously allocated bio.
So these to places which both handle failure and hold multiple bios
should not use bio_alloc, they should use bio_kmalloc.
