[PATCH net] net: sunhme: Return an error when we are out of slots

[Sean Anderson]

We only allocate enough space for four devices when the parent is a QFE. If
we couldn't find a spot (because five devices were created for whatever
reason), we would not return an error from probe(). Return ENODEV, which
was what we did before.

Fixes: 96c6e9faecf1 ("sunhme: forward the error code from pci_enable_device()")
