Correct a problem with the user process scheduler's estimated cpu
calculation.  lwp_slptime would sometimes not get reset to 0 after a
wakeup and cause a cpu-bound process to get more cpu then it deserves.

Move the estcpu call for calculations based on slptime to the tsleep code
and then unconditionally set lwp_slptime back to 0 after the process
wakes up again.
