x86_64: Fix to keep watchdog disabled by default for i386/x86_64
Fixed wrong expression which enabled watchdogs even if nmi_watchdog kernel parameter wasn't set. This regression got slightly introduced with commit b7471c6da94d30d3deadc55986cc38d1ff57f9ca. Introduced NMI_DISABLED (-1) which allows to switch the value of NMI_DEFAULT without breaking the APIC NMI watchdog code (again). Fixes: https://bugzilla.novell.com/show_bug.cgi?id=298084 http://bugzilla.kernel.org/show_bug.cgi?id=7839 And likely some more nmi_watchdog=0 related issues.
