btrfs: reflink: initialize return value to 0 in btrfs_extent_same()
Fix a warning reported by smatch that ret could be returned without
initialized. The dedupe operations are supposed to to return 0 for a 0
length range but the caller does not pass olen == 0. To keep this
behaviour and also fix the warning initialize ret to 0.
