Ian Dowse 4202b366fc Oops, when trying the dirhash sequential-access optimisation,
compare the slot offset against the predicted offset, not a boolean
flag. This typo effectively disabled the sequential optimisation,
but was otherwise harmless.

Not surprisingly, fixing this improves performance in the sequential
access case. I am seeing a 7% speedup on one machine here; using
dirhash when sequentially looking up directory entries is now about
5% faster instead of 2% slower than the non-dirhash case.
