bool_t Check_nfs4_seqid	(	state_owner_t *	powner,
		seqid4	seqid,
		nfs_argop4 *	args,
		compound_data_t *	data,
		nfs_resop4 *	resp,
		const char *	tag
	)

Check_nfs4_seqid: Check NFS4 request for valid seqid for replay, next request, or BAD_SEQID.

Returns TRUE if the request is the next seqid. If the request is a replay, copies the saved response and returns FALSE. Otherwise, sets status to NFS4ERR_BAD_SEQID and returns FALSE.

In either case, on a FALSE return, the caller should send the resulting response back to the client.
