watchdog: at91rm9200: Only warn once about problems in .remove() 

The single difference between returning 0 and returning an error code in
a platform remove callback is that in the latter case the platform core
emits a warning about the error being ignored.

at91wdt_remove() already emits a warning in the error case, so suppress
the more generic (and less helpful) one by returning 0.
