tlan_probe1() enables the PCI device with pci_enable_device().

The probe failure path disables the device with pci_disable_device().
However, after a successful probe, tlan_remove_one() releases the PCI
regions and frees the net device without disabling the PCI device.

Call pci_disable_device() during removal to balance the successful
pci_enable_device() call.

This issue was found by manual code inspection.

I don't think that you need the #ifdef and #endif lines
as I believe that there is a noop implementation
of pci_disable_device when CONFIG_PCI is not set.

Sashiko seems to think so too:
