The problem is introduced by e8368b57c006 ("blk-throttle: use
calculate_io/bytes_allowed() for throtl_trim_slice()").
tg_iops_limit return U64_MAX and overflow occur in
calculate_io_allowed(). This bug has always existed, but it did not
cause kernel crash before.
If we didn't enable throttle of iops, we shouldn't calculate its limit.
ios is also. I will fix it later.

More specifically, before e8368b57c006, the calculation is:
tmp = U64_MAX * 100;
do_div(tmp, HZ)
After e8368b57c006:
mul_u64_u64_div_u64(U64_max, 100, HZ)
This new helper is supposed to avoid overflow, however, I have no idea
why mul_u64_u64_div_u64() will trigger divide 0 error, this problem
seems related to this helper.
Anyway, for blk-throttle, when bps_limit is U64_MAX, throtl_trim_slice
should not update bytes/io_disp in the first place, and this calculation
can be avoided.
Thanks,
Kuai
