btrfs: use unsigned types for constants defined as bit shifts
[ Upstream commit 05a6ec865d091fe8244657df8063f74e704d1711 ]
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.
