ceph: fix xattr cap writeback
We should include the xattr metadata blob in the cap update message any time we are flushing dirty state, NOT just when we are also dropping the cap. This fixes async xattr writeback. Also, clean up the code slightly to avoid duplicating the bit test. Signed-off-by: Sage Weil <sage@newdream.net>
