watchdog: Fix non-standard prototype of get_softlockup_thresh()

This build warning slipped through:

  kernel/watchdog.c:102: warning: function declaration isn't a prototype

As reported by Stephen Rothwell.

Also address an unused variable warning that GCC 4.6.0 reports:
we cannot do anything about failed watchdog ops during CPU hotplug
(it's not serious enough to return an error from the notifier),
so ignore them.
