r14986: Fix OS/2 directory delete bug found by kukks.

Browse Source 
(Thanks a lot for all your hard work on this).
We were caching the results of *all* directory
scans, not just the results that match the
client wildcard. This actually made no sense,
as only matches on the client wildcard can be
returned to the client and so might need to
be searched for in the cache. This fixes the
directory cache to only cache entries that we
return to the client.
Jeremy.
