staging: comedi: change comedi_alloc_board_minor() to return pointer

Change `comedi_alloc_board_minor()` to return a pointer to the allocated
`struct comedi_device` instead of a minor device number.  Return an
`ERR_PTR()` value on error instead of a negative error number.  This
saves a call to `comedi_dev_from_minor()` in `comedi_auto_config()`.

Also change it to use a local variable `dev` to hold the pointer to the
`struct comedi_device` instead of using `info->device` all the time.
