Subject: [PATCH net-next v3 8/9] net: sunhme: Inline error returns

The err_out label used to have cleanup. Now that it just returns, inline it
everywhere. While we're at it, fix an uninitialized return code if we never
found a qfe slot.

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