[PATCH] Make touch_nmi_watchdog imply touch_softlockup_watchdog on all archs

[Michal Schmidt <xschmi00@stud.feec.vutbr.cz>]

touch_nmi_watchdog() calls touch_softlockup_watchdog() on both
architectures that implement it (i386 and x86_64). On other architectures
it does nothing at all. touch_nmi_watchdog() should imply
touch_softlockup_watchdog() on all architectures.
Suggested by Andi Kleen.
