[Qemu-devel] [PULL v2 2/2] hw/block/pflash_cfi02: Rewrite a fall through comment

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

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

  hw/block/pflash_cfi02.c: In function ‘pflash_write’:
  hw/block/pflash_cfi02.c:574:16: error: this statement may fall through [-Werror=implicit-fallthrough=]
    574 |             if (boff == 0x55 && cmd == 0x98) {
        |                ^
  hw/block/pflash_cfi02.c:581:9: note: here
    581 |         default:
        |         ^~~~~~~
  cc1: all warnings being treated as errors

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