<div class='commit-subject'>fix race in d_splice_alias()</div><div class='commit-msg'>rehashing the negative placeholder opens a race with d_lookup();
we unhash it almost immediately (by d_move()), but the race
window is there.  Since d_move() doesn't rely on target being
hashed, we don't need that d_rehash() at all.
