[ Upstream commit e99812e1382f0bfb6149393262bc70645c9f537a ]
We can't use nfs4_fattr_bitmap as a bitmask, because it hasn't been filtered to represent the attributes supported by the server. Instead, let's revert to using server->cache_consistency_bitmask after adding in the missing SPACE_USED attribute.
