As interp_forward is type bool assignment to a logical operation directly
is sufficient here.

./kernel/time/timekeeping.c:1000:9-14: WARNING: conversion to bool not needed he
re
The explicit conversion to bool is not needed here as the logical operator
ensures that the right-side is a bool anyway.

Patch was compiletested with: x86_64_defconfig

Patch is against 4.11-rc3 (localversion-next is next-20170324)

timekeeping: Remove pointless conversion to bool

interp_forward is type bool so assignment from a logical operation directly
is sufficient.
