softlockup: Stop spurious softlockup messages due to overflow
commit 8c2eb4805d422bdbf60ba00ff233c794d23c3c00 upstream.
Ensure additions on touch_ts do not overflow. This can occur
when the top 32 bits of the TSC reach 0xffffffff causing
additions to touch_ts to overflow and this in turn generates
spurious softlockup warnings.
