[netdrvr 8139cp] PCI MWI cleanup; remove unneeded workaround

* The PCI layer now handles incorrect cacheline size settings, as it should. Remove our own workarounds.
* Move pci_set_mwi up much earlier in the probe process, and check its return value.
* Call pci_clear_mwi() in ->probe error handling
* Call pci_clear_mwi() in ->remove

[netdrvr 8139too] remove driver-based poisoning of net_device
