netxen: unregister notifiers if PCI registration fails

netxen_init_module() registers the netdevice and inetaddr notifiers before
registering the PCI driver.  If pci_register_driver() fails, the function
returns the error directly and leaves both notifiers registered.

That leaves notifier callbacks installed for a module that failed to load.
Mirror the module exit path on this failure and unregister the notifiers
before returning the error.
