From: Steve French <stfrench@xxxxxxxxxxxxx> commit c1f8a398b6d661b594556a91224b096d92293061 upstream. Mounting with "multichannel" is obviously implied if user requested more than one channel on mount (ie mount parm max_channels>1). Currently both have to be specified. Fix that so that if max_channels is greater than 1 on mount, enable multichannel rather than silently falling back to non-multichannel.
