staging: comedi_pci: pass comedi_device to comedi_pci_enable()

Make comedi_pci_enable() use the same parameter type as
comedi_pci_disable(). This also allows comedi_pci_enable
to automatically determine the resource name passed to
pci_request_regions().

Make sure the errno value returned is passed on instead of
assuming an errno. Also, remove any kernel noise that is
generated when the call fails.

The National Instruments drivers that use the mite module
currently enable the PCI device in the mite module. For
those drivers move the call to comedi_pci_enable into the
driver.
