Make SI2q compatible with dynamically updated SI via RSL
After SI2q configuration is changed via vty, the SI messages can be regenerated using
bts 0 resend-system-information command. That should lead to proper update of SI2q index and count (if number of messages has changed) and should be propagated to RSL accordingly.
Right now only last message (7/7 for example) got properly updated count, others still use old value.
Note: this is for BSC-side fix, the BTS side should be fixed by gerrit 3180.
