[Dan Williams]

Use "fallthrough;" to address:

tools/testing/nvdimm/test/nfit.c: In function ‘nd_intel_test_finish_query’:
tools/testing/nvdimm/test/nfit.c:436:37: warning: this statement may
        fall through [-Wimplicit-fallthrough=]
  436 |                 fw->missed_activate = false;
      |                 ~~~~~~~~~~~~~~~~~~~~^~~~~~~
tools/testing/nvdimm/test/nfit.c:438:9: note: here
  438 |         case FW_STATE_UPDATED:
      |         ^~~~
