Source kernel commit: deb06b9ab6dfa167c280a68d5acb2f12e007073f
The @start pointer passed to each per-AG btree type's ->alloc_block
function isn't supposed to be modified, since it's a hint about the
location of the btree block being split that is to be fed to the
allocator, so mark the parameter const.
