Stefan Berger 0b31e28fbd ima: Fix use-after-free on a dentry's dname.name
commit be84f32bb2 upstream.

->d_name.name can change on rename and the earlier value can be freed;
there are conditions sufficient to stabilize it (->d_lock on dentry,
->d_lock on its parent, ->i_rwsem exclusive on the parent's inode,
rename_lock), but none of those are met at any of the sites. Take a stable
snapshot of the name instead.
