can: rcar_can: fix IRQ check
rcar_can_probe() regards 0 as a wrong IRQ #, despite platform_get_irq() that it
calls returns negative error code in that case. This leads to the following
being printed to the console when attempting to open the device:
error requesting interrupt fffffffa
because rcar_can_open() calls request_irq() with a negative IRQ #, and that
function naturally fails with -EINVAL.
Check for the negative error codes instead and propagate them upstream instead
of just returning -ENODEV.
Fixes: fd1159318e55 ("can: add Renesas R-Car CAN driver")
