Subject[PATCH] net: spider_net: Mark expected switch fall-through
Mark switch cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/net/ethernet/toshiba/spider_net.c: In function 'spider_net_release_tx_chain':
drivers/net/ethernet/toshiba/spider_net.c:783:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!brutal) {
^
drivers/net/ethernet/toshiba/spider_net.c:792:3: note: here
case SPIDER_NET_DESCR_RESPONSE_ERROR:
^~~~

Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
