hw/net/can/xlnx-versal-canfd: Fix interrupt level

The interrupt level should be 0 or 1. The existing code was using the
interrupt flags to determine the level. In the only machine currently
supported (xlnx-versal-virt), the GICv3 was masking off all bits except
bit 0 when applying it, resulting in the IRQ never being delivered.
