[PATCH] net: sungem: disable PCI device on remove

[Guangshuo Li]

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

The probe failure path balances this operation with
pci_disable_device(). However, after a successful probe,
gem_remove_one() releases the PCI resources and netdev 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.
