Chris Mason 389f239c53 btrfs: make sure we stay inside the bvec during __btrfs_lookup_bio_sums 
Commit c40a3d38af (Btrfs: Compute and look up csums based on
sectorsized blocks) changes around how we walk the bios while looking up
crcs.  There's an inner loop that is jumping to the next bvec based on
sectors and before it derefs the next bvec, it needs to make sure we're
still in the bio.

In this case, the outer loop would have decided to stop moving forward
too, and the bvec deref is never actually used for anything.  But
CONFIG_DEBUG_PAGEALLOC catches it because we're outside our bio.
