watchdog: permit `wd 0` for non-stoppable, but inactive, watchdogs
A watchdog that can't be stopped returns -ENOSYS on set_timeout(0).
If the watchdog supports communicating whether it's running, we could
still allow `wd 0`, if it hasn't been started yet.
Setting device parameter .priority=0 disables a watchdog. One would
expect this to always succeed for a not-running watchdog, but currently
it doesn't, if the driver's set_timeout(0) returns -ENOSYS. With this
fix, this is supported making the user API less surprising.
