[PATCH] staging: dgnc: Remove useless and deadly judgment

[navych@126.com (Navy Cheng)]

pci_unregister_driver() should be used once dgnc module exit. It has
nothing to do with dgnc_NumBoards. Remove the judgment of dgnc_NumBoards to
avoid pci_unregister_driver() is not used when dgnc_NumBoards is 0.
