qemu: command: don't overwrite watchdog dump action

The watchdog cli refactoring in 4666b762 dropped the temporary variable
we use to convert to action=dump to action=pause for the qemu cli, and
stored the converted value in the domain structure. Our other watchdog
handling code then treated it as though the user requested action=pause,
which broke action=dump handling.

Revive the temporary variable to fix things.
