Sergei Shtylyov dfe8266d54 can: rcar_can: fix IRQ check 
commit 5e63e6baa1 upstream.

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: fd1159318e ("can: add Renesas R-Car CAN driver")
