dgnc_cleanup_module() was called when the module unloaded to do a total
cleanup and it was also called if pci_register_driver() fails. But
dgnc_cleanup_module() will try dgnc_remove_driver_sysfiles() but the
sysfiles will be created only if pci_register_driver() succeeds.
So if pci_register_driver() fails and we try dgnc_cleanup_module() then we
were getting:

[  942.001479] BUG: unable to handle kernel NULL pointer dereference at 00000018

We may choose to load the module without the hardware present. That will
register the pci driver but since probe will not succeed so
dgnc_NumBoards will be 0. Now if we unload the module then the pci
driver stays registered as dgnc_NumBoards is 0. And if we try to load
the module again it fails with the error:
"Driver 'dgnc' is already registered."

If pci_register_driver() fails then dgnc_NumBoards can never be more
than zero. dgnc_NumBoards is incremented only at the end of a successful
probe. And moreover if the pci driver has failed to register then we
never need to unregister it. Lets just print the warning, perform the
cleanup and exit with the error code.
