x86: fix watchdog ops for CoreDuo

x86: fix watchdog ops for CoreDuo

There apparently was an unnoticed conflict between an earlier patch to
this file and mine (64778fff6c144d39d14c5986fb19546adbdd8990), which
I noticed only now. I suppose a change like the one below (untested) is
needed; I didn't get any response on a confirmation request for this from
the submitter of the first patch.

The issue is the writing of the 'checkbit' member at the end of
setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops
rather than wd_ops.
