vl: Rewrite a fall through comment

GCC9 is confused by this comment when building with CFLAG
-Wimplicit-fallthrough=2:

  vl.c: In function ‘qemu_ref_timedate’:
  vl.c:773:15: error: this statement may fall through [-Werror=implicit-fallthrough=]
    773 |         value -= rtc_realtime_clock_offset;
        |         ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~
  vl.c:775:5: note: here
    775 |     case QEMU_CLOCK_VIRTUAL:
        |     ^~~~
  cc1: all warnings being treated as errors

Rewrite the comment using 'fall through' which is recognized by
GCC and static analyzers.
