Bluetooth: Fix 'SendRRorRNR' to send the ReqSeq value



SendRRorRNR needs to acknowledge received I-frames (actually every packet
needs to acknowledge received I-frames by sending the proper packet
sequence number), so ReqSeq is set to the next I-frame number sequence to
be pulled by the reassembly function.
SendRRorRNR tells the remote side about local busy conditions, it sends
a Receiver Ready frame if local busy is false or a Receiver Not Ready
if local busy is true.
ReqSeq is the packet's field to send the number of the acknowledged
packets.
