staging: comedi: ni_daq_700: refactor the pcmcia attach/detach

Browse source

Move the pcmcia_disable_device() call where needed in the
pcmcia attach/detach and delete the dio700_release() function.

Move the logic of dio700_config() directly into the attach
function and properly return an error code when the config
fails.

Only set the pcmcia_cur_dev, used by the comedi_driver, if
the pcmcia attach is successful. Also, make sure to NULL it
in the detach.

Remove all the kernel messages in the pcmcia support code. They
are just added noise.
