[janitor] update the atarilance Ethernet driver for VME Lance cards on the Atari to check the result of request_irq and exit in case of error.

Patch is also available at the following URL
        http://www.chez.com/wstinson/linux/kernel/patch-net-atari

I don't have this hardware to check for myself
