    jiffies: Revert bogus conversion of NSEC_PER_SEC to TICK_NSEC
    Frederic Weisbecker authored and Thomas Gleixner committed 
    commit 93825f2e converted NSEC_PER_SEC to TICK_NSEC because the author
confused NSEC_PER_JIFFY with NSEC_PER_SEC.

As a result, the calculation of refined jiffies got broken, triggering
lockups.

Fixes: 93825f2e ("jiffies: Reuse TICK_NSEC instead of NSEC_PER_JIFFY")
