nvic: Fix miscalculation of offsets into ITNS array
This calculation of the first exception vector in the ITNS<n> register being accessed: int startvec = 32 * (offset - 0x380) + NVIC_FIRST_IRQ; is incorrect, because offset is in bytes, so we only want to multiply by 8. Spotted by Coverity (CID 1381484, CID 1381488), though it is not correct that it actually overflows the buffer, because we have a 'startvec + i < s->num_irq' guard.
