bcachefs: Replace div_u64 with div64_u64 where second param is u64
Bcachefs often uses this function to divide by nanosecond times - which
can easily cause problems when cast to u32. For example, `cat
/sys/fs/bcachefs/*/internal/rebalance_status` would return invalid data
in the `duration waited` field because dividing by the number of
nanoseconds in a minute requires the divisor parameter to be u64.
