xfs: abort dir/attr btree operation if btree is obviously weird Abort an dir/attr btree operation if the attr btree has obvious problems like loops back to the root or pointers don't point down the tree. Found by fuzzing btree[0].before to zero in xfs/402, which livelocks on the cycle in the attr btree. Apply the same checks to xfs_da3_node_lookup_int. Signed-off-by: Darrick J.
