ntp: Fix integer overflow when setting time
commit a078c6d0e6288fad6d83fb6d5edd91ddb7b6ab33 upstream.
'long secs' is passed as divisor to div_s64, which accepts a 32bit
divisor. On 64bit machines that value is trimmed back from 8 bytes
back to 4, causing a divide by zero when the number is bigger than
(1 << 32) - 1 and all 32 lower bits are 0.
Use div64_long() instead.
