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.
Fixes: ed58f2e66e84 ("btrfs: backref, don't add refs from shared block when resolving normal backref")
