fix race in d_splice_alias() 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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
