can: mcba_usb: fix device disconnect bug
Currently, when you disconnect the device, the driver infinitely
resubmits all URBs, so you see:
Rx URB aborted (-32)
in an infinite loop.
Fix this by catching -EPIPE (what we get in urb->status when the device
disconnects) and not resubmitting.
With this patch, I can plug and unplug many times and the driver
recovers correctly.
