tankinfomodel.cpp: clamp row index to [0 - MAX_TANK_INFO]

Browse source 
MAX_TANK_INFO is a new macro in dive.h to define the
maximum number of tank_info_t objects.

TankInfoModel's data() and setData() now check for valid
row indexes before accessing the tank_info[] array directly.

Without this patch TankInfoMode::data() can cause a SIGSEGV.
