[PATCH v3 01/10] watchdog: wdt-uclass.c: use wdt_start() in wdt_expire_now()

[Rasmus Villemoes]

wdt_start() does the "no ->start? return -ENOSYS" check, don't
open-code that in wdt_expire_now().

Also, wdt_start() maintains some global (and later some per-device)
state, which would get out of sync with this direct method call - not
that it matters much here since the board is supposed to reset very
soon.
