[PATCH] Don't run unlock_super() in ext3_fill_super()

A very long time ago ext3_fill_super() was beng called under the VFS's
lock_super(), and it had to drop that lock for deadlock avoidance reasons.

But the VFS was later changed to not take lock_super() across ->fill_super(),
so we're upping a non-downed semaphore.

Just take it out.
