watchdog: smsc37b787_wdt: Mark expected switch fall-through

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/watchdog/smsc37b787_wdt.c: In function ‘wb_smsc_wdt_ioctl’:
drivers/watchdog/smsc37b787_wdt.c:480:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   wb_smsc_wdt_set_timeout(timeout);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/watchdog/smsc37b787_wdt.c:482:2: note: here
  case WDIOC_GETTIMEOUT:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

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

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
