btrfs: use unsigned types for constants defined as bit shifts
The unsigned type is a recommended practice (CWE-190, CWE-194) for bit shifts to avoid problems with potential unwanted sign extensions. Although there are no such cases in btrfs codebase, follow the recommendation. Reviewed-by: Boris Burkov <boris@bur.io> Signed-off-by: David Sterba <dsterba@suse.com>
