btrfs: use test_and_set_bit() in btrfs_delayed_delete_inode_ref()

Browse Source 
Instead of testing and setting the BTRFS_DELAYED_NODE_DEL_IREF bit in the
delayed node's flags, use test_and_set_bit() which makes the code shorter
without compromising readability and getting rid of the label and goto.
