ceph: disable use of dcache for readdir etc.
Ceph attempts to use the dcache to satisfy negative lookups and readdir when the entire directory contents are in cache. Disable this behavior until lingering bugs in this code are shaken out; we'll re-enable these hooks once things are fully stable. Signed-off-by: Sage Weil <sage@newdream.net>
