ncpfs: replace BKL with lock_super

Err, no.  lock_super is just as much on it's way out as the BKL.  We've
managed to move it down from the VFS into a few remaining filesystems
and now need to get rid of those users.  Please don't add any new ones.

Ok. I guess that's also a NAK for my the isofs patch I posted yesterday
then. Do you have any suggestions for an alternative approach?

Just add a per-sb mutex inside the filesystem.  Given that lock_super
isn't used by the VFS anymore that's actually equivalent.
