It might happen that the NIT table doesn't get parsed.
As reported by Olcay, some transponders at Turksat-42.0E seem
to be missing the NIT table, causing dvb tools to crash with:
Program received signal SIGSEGV, Segmentation fault.
dvb_store_channel (dvb_file=0x7fffffffe460, __p=0x5555555605d0,
dvb_scan_handler=0x555555565060, get_detected=0,
get_nit=0) at dvb-file.c:1345
1345 if (dvb_scan_handler->nit->transport) {
As both transport ID and network ID are optional information,
verify if the nit table was parsed before trying fill them.
