ice: Use div64_u64 instead of div_u64 in adjfine

[ Upstream commit 0013881c1145d36bf26165bb70fdd7560a5507a3 ]

Change the division in ice_ptp_adjfine from div_u64 to div64_u64.
div_u64 is used when the divisor is 32 bit but in this case incval is
64 bit and it caused incorrect calculations and incval adjustments.
