NFSv4: Don't ignore the NFS_INO_REVAL_FORCED flag in nfs_revalidate_inode()
If the NFS_INO_REVAL_FORCED flag is set, that means that we don't yet have an up to date attribute cache. Even if we hold a delegation, we must put a GETATTR on the wire. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: stable@kernel.org
