btrfs: sanitizing ->fs_info, part 4
A new helper: btrfs_alloc_root(fs_info); allocates btrfs_root
and sets ->fs_info. All places allocating the suckers converted
to it. At that point we *never* reassign ->fs_info of btrfs_root;
it's set before anyone sees the address of newly allocated
struct btrfs_root and never assigned anywhere else.
