tipc: simplify tipc_link_rcv() reception loop
Currently, all packets received in tipc_link_rcv() are unconditionally added to the packet deferred queue, whereafter that queue is walked and all its buffers evaluated for delivery. This is both non-optimal and and makes the queue sorting function unnecessary complex. This commit changes the loop so that an arrived packet is evaluated first, and added to the deferred queue only when a sequence number gap is discovered. A non-empty deferred queue is walked until it is empty or until its head's sequence number doesn't fit.
