staging: comedi: das08: No need to manipulate PCI ref count
Now that this driver no longer supports "manual" attachment of PCI
devices in its `attach` hook (`das08_attach()`), it no longer has code
that searches for a suitable PCI device and increments its reference
count. Since the driver no longer has any reason for incrementing and
decrementing the PCI device's reference count, the calls to
`pci_dev_get()` and `pci_dev_put()` can be removed.
