Fixed LLCP receive window checkings.
Before sending a packet, the LLCP stack have to check if the remote
peer is ready to send. To do so, a Receive Window mechanism based on
packet numbering and acknowledgment is used.
Basically, the sender have to make sure that he must have not sent
more than RW-1 unaknowledged frames before sending a new one. This
patch is correcting this test which was failing in some situations.
