HID: nintendo: check analog user calibration for plausibility

  Cheap clone controllers may (falsely) report as having a user
  calibration for the analog sticks in place, but return
  wrong/impossible values for the actual calibration data.
  In the present case at mine, the controller reports having a
  user calibration in place and successfully executes the read
  commands. The reported user calibration however is
  min = center = max = 0.

  This pull request addresses problems of this kind by checking the
  provided user calibration-data for plausibility (min < center < max)
  and falling back to the default values if implausible.

I'll note that I was experiencing a crash because of this bug when using
the GuliKit KingKong 2 controller. The crash manifests as a divide by
zero error in the kernel logs:
kernel: divide error: 0000 [#1] PREEMPT SMP NOPTI
