hrtimers: Fix typo causing erratic timers
commit 9ec2690758a5 ("timerfd: Manage cancelable timers in timerfd") introduced a CONFIG_HIGHRES_TIMERS (should be CONFIG_HIGH_RES_TIMERS) typo, which caused applications depending on CLOCK_REALTIME timers to become sluggy due to the fact that the time base of the realtime timers was not updated when the wall clock time was set. This causes anything from 100% CPU use for some applications to odd delays and hickups.
