3.13.y: timekeeping: Fix clock_set/clock_was_set think-o

In backporting 6fdda9a9c5db367130cf32df5d6618d08b89f46a
(timekeeping: Avoid possible deadlock from clock_was_set_delayed),
I ralized the patch had a think-o where instead of checking
clock_set I accidentally typed clock_was_set (which is a function
- so the conditional always is true).

Upstream this was resolved in the immediately following patch
47a1b796306356f358e515149d86baf0cc6bf007 (tick/timekeeping: Call
update_wall_time outside the jiffies lock). But since that patch
really isn't -stable material, so this patch only pulls
the name change.
