bufferhead: revert constructor removal
The constructor for buffer_head slabs was removed recently. We need the
constructor back in slab defrag in order to insure that slab objects always
have a definite state even before we allocated them.
I think we mistakenly merged the removal of the constuctor into a cleanup
patch. You (ie: akpm) had a test that showed that the removal of the
constructor led to a small regression. The prior state makes things easier
for slab defrag.
