ceph: getattr before read on ceph.* xattrs
Previously we were returning values for quota, layout
xattrs without any kind of update -- the user just got
whatever happened to be in our cache.
Clearly this extra round trip has a cost, but reads of
these xattrs are fairly rare, happening on admin
intervention rather than in normal operation.
