xfs: remove xfs_attr_leaf_hasname
The calling convention of xfs_attr_leaf_hasname() is problematic, because
it returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer
when xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a
non-NULL buffer pointer for an already released buffer when
xfs_attr3_leaf_lookup_int fails with other error values.
Fix this by simply open coding xfs_attr_leaf_hasname in the callers, so
that the buffer release code is done by each caller of
xfs_attr3_leaf_read.
