btrfs: set AS_KERNEL_FILE on the btree_inode
extent_buffers are global and shared so their pages should not belong to
any particular cgroup (currently whichever cgroups happens to allocate the
extent_buffer).
Btrfs tree operations should not arbitrarily block on cgroup reclaim or
have the shared extent_buffer pages on a cgroup's reclaim lists.
