hw/net/imx_fec: Rewrite fall through comments

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

  hw/net/imx_fec.c: In function ‘imx_eth_write’:
  hw/net/imx_fec.c:906:12: error: this statement may fall through [-Werror=implicit-fallthrough=]
    906 |         if (unlikely(single_tx_ring)) {
        |            ^
  hw/net/imx_fec.c:912:5: note: here
    912 |     case ENET_TDAR:     /* FALLTHROUGH */
        |     ^~~~
  cc1: all warnings being treated as errors

Rewrite the comments in the correct place,  using 'fall through'
which is recognized by GCC and static analyzers.
