staging: comedi: don't call attach_pci handler

All the Comedi drivers that call `comedi_pci_auto_config()` have
replaced the `attach_pci()` handler in their `struct comedi_driver` with
a `auto_attach()` handler, so there is no need to check for the
existence of the `attach_pci()` handler any more.  Remove this check and
the code that calls it.
