staging: comedi: ni_daq_dio24: cleanup pcmcia probe/remove

Absorb the code from dio24_config() into the probe function,
dio24_cs_attach() and properly return the error code when the
probe fails. This also gets rid of an unnecessary forward
declaration.

For aesthetic reasons, move the remove functio, dio24_cs_detach(),
so it's after the probe function.

Remove a number of dev_{level} noise messages in the probe/remove
functions.
