Summary:                    [patch] fisu_rx doesn't request retransmission when
it should
Description: 
fisu_rx doesn't check if a retransmission request is needed when the last
received message was a FISU, so in a case like:

FISU FSN=3
MSU FSN=4 lost
FISU FSN=4

fisu_rx says "last message received was a FISU, so this one is just a
repetition, ignore it" and misses the need to ask for a retransmission.

Fix MTP2 so that we check for potential need for retransmission even on
repeated FISUs. (https://issues.asterisk.org/view.php?id=18393)
