hrtimer: fix signed/unsigned bug in slack estimator
the slack estimator used unsigned math; however for very short delay it's
possible that by the time you calculate the timeout, it's already passed and
you get a negative time/slack... in an unsigned variable... which then gets
turned into a 100 msec delay rather than zero.
This patch fixes this by using a signed typee in the right places.
