Your initialization code should

1.) Select the CANIRQ as IRQ (not FIQ).
2.) Enable the interrupt on a specific pos.
3.) Set the IRQ routine address.
4.) Enable the CAN interrupt.

Sample for I2C below

// initialize the interrupt vector
VICIntSelect &= ~VIC_BIT (VIC_I2C0 );    // I2C selected as IRQ
VICVectCntl2 = VIC_ENABLE | VIC_I2C0;
VICVectAddr2 = (uint32_t)I2CISR;            // address of the ISR
VICIntEnable = VIC_BIT( VIC_I2C0 );        // I2C interrupt enabled
