fast_dput(): new rules for refcount
By now there is only one place in entire fast_dput() where we return
false; that happens after refcount had been decremented and found (under
->d_lock) to be zero. In that case, just prior to returning false to
caller, fast_dput() forcibly changes the refcount from 0 to 1.
Lift that resetting refcount to 1 into the callers; later in the series
it will be massaged out of existence.
