Subject: [PATCH 14/18] Bluetooth: Fix 'SendRRorRNR' to send the ReqSeq value

From: Gustavo F. Padovan <gustavo@....ic.unicamp.br>

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.
