Wen Yang 62658ebe5c timekeeping: Prevent 32bit truncation in scale64_check_overflow() 
[ Upstream commit 4cbbc3a0ee ]

While unlikely the divisor in scale64_check_overflow() could be >= 32bit in
scale64_check_overflow(). do_div() truncates the divisor to 32bit at least
on 32bit platforms.

Use div64_u64() instead to avoid the truncation to 32-bit.
