NFSv4: Don't ignore the NFS_INO_REVAL_FORCED flag in nfs_revalidate_inode()
commit b4d2314bb88b07e5a04e6c75b442a1dfcd60e340 upstream.
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.
