NFS: Fix attribute bitmask in _nfs42_proc_fallocate()

NFS: Fix attribute bitmask in _nfs42_proc_fallocate()

[ 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.
