x86: add the word 'WARNING' in check_nmi_watchdog() output
Our automated test suite looks for keywords like error, fail, warning in
the boot log. In the case when the nmi watchdog is determined to be
stuck in check_nmi_watchdog(), none of those keywords are displayed.
This patch adds a keyword, "WARNING:", so it makes it easier to notice
when the nmi watchdog isn't working correctly. Also add a proper
KERN_WARNING mark to this printout.
