btrfs: fix gcc-4.8 build warning for struct initializer
Some older compilers like gcc-4.8 warn about mismatched curly braces in a initializer: fs/btrfs/backref.c: In function 'is_shared_data_backref': fs/btrfs/backref.c:394:9: error: missing braces around initializer [-Werror=missing-braces] struct prelim_ref target = {0}; ^ fs/btrfs/backref.c:394:9: error: (near initialization for 'target.rbnode') [-Werror=missing-braces] Use the GNU empty initializer extension to avoid this.
