watchdog: Differentiate scenarios when watchdog is closed

Presently, when a watchdog device is closed, we print "watchdog did not
stop" in a few different scenarios;

1. When nowayout is set
2. When the watchdog is able to close, has received the magic character
   to stop, but fails to close in device-specific code paths
3. When userspace deliberately closes it without stopping it

For 1, we explicitly print we can not close because of nowayout. Nothing
differentiates the other two however.

This change adds a print to indicate the watchdog was closed while still
running.
