Since commit 8e5cfb55d3f (Btrfs: Make raid_map array be inlined in
btrfs_bio structure), the raid map array is allocated along with the
btrfs bio in alloc_btrfs_bio. The calculation used to decide how
much
we need to allocate was using the wrong parameter passed into the
allocation function.
The passed in real_stripes will be zero if a target replace
operation
is not currently running. We want to use total_stripes instead.

Current master + this patch with full slub_debug is now ok with
btrfs/023.
Thanks Dave. It also survived all night with raid6 and stress.sh. I'm
sending to Linus today.
