3c59x: check return of pci_enable_device()
Check return of pci_enable_device in vortex_up(). Also modify vortex_up to return error to callers. Handle failure of vortex_up in vortex_open and vortex_resume. Signed-off-by: Mark Hindley <mark@hindley.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>
