Frank Rowand 1adc86798f of: some unittest overlays not untracked
kernel test robot reported "WARNING: held lock freed!" triggered by
unittest_gpio_remove(), which should not have been called because
the related gpio overlay was not tracked.  Another overlay that
was tracked had previously used the same id as the gpio overlay
but had not been untracked when the overlay was removed.  Thus the
clean up function of_unittest_destroy_tracked_overlays() incorrectly
attempted to remove the reused overlay id.

Patch contents:

  - Create tracking related helper functions
  - Change BUG() to WARN_ON() for overlay id related issues
  - Add some additional error checking for valid overlay id values
  - Add the missing overlay untrack
  - update comment on expectation that overlay ids are assigned in
    sequence
