bsc_init: Forget which SIs are valid for the trx 

Previously the SI generation lead to setting the BCCH SIs for all TRX in
a multi-trx setup. This is because we create the SIs globally but
si_valid appears to be limited to the 'current' trx. Warn if we attempt
to set SIs for the BCCH on a trx that does not have a BCCH.
