No memory leaks there.  Note that ->kill_sb() is called in *all*
cases, so that kfree() will be done by it just fine.

It's *not* ->put_super() - that would've been called only for superblocks
that had passed mount.  ->kill_sb() is called for *all* of them and
that often simplifies cleanup on failure exits quite nicely.
