Sorry for my poor English ,and poor commit message, this bring
trouble for more than one maintainer, I guess.

The old code use below comparion as condition to terminate valid
range check without care whether there are more ranges in later
if (start == 0)

I guess original author think (or make a mistake) when we meet a
address range begin from zero means it is a invalid address range,
and no valid address ranges in remain BARs.

So I said:
We can't break the loop when meet range whose start address is zero,
without check it and remaining BARs' range.
