Revert "use on_hid_hw_open instead of input_dev->open"

This reverts commit c26573d77369c042dc2b9a881a7f2ff88ddc0dd9.

+ `on_hid_hw_open` is apparently new enough that common distros don't
  have it yet, so let's wait a few years and try again. The old method
  works well enough and if not, just set `open_mode=0`.
