I think the assertion is bogus. It was correct before the xattr support
was added.

The assertion basically is: if the inode is a directory inode, it should
not have data in it.

In that function, dir_ui (directory UBIFS inode) may be also be the
"host" inode for the xattr entry, so it is not necessarily a directory
inode at all.

So the variable should be re-named to "host_ui" instead of "dir_ui".
