Line 216 of xfs_attr_leaf.c: in 3.13 is:
if (!xfs_attr3_leaf_verify(bp)) {
XFS_CORRUPTION_ERROR(__func__, XFS_ERRLEVEL_LOW, mp,
bp->b_addr);

So xfs_attr3_leaf_verify() only checks these 2 things:
if (ichdr.magic != XFS_ATTR_LEAF_MAGIC)
return false;
that magic is 0xfbee, so good there... and:
if (ichdr.count == 0)
return false;
so that's the problem, apparently. If I'm reading it correctly, it's trying
to write an empty attribute block to disk; this shouldn't happen.
If you have traces, perhaps we can see which inode it's working on, and learn
something
from examining it in xfs_db...
