USB: Only treat lasting over-current conditions as errors
On a laptop I see these errors on (most) resumes:
hub 3-0:1.0: over-current change on port 1
hub 3-0:1.0: over-current change on port 2
Since over-current conditions can disappear quite quickly it's better to
downgrade that message to debug level, recheck for an over-current
condition a little later and only print and over-current condition error
if that condition (still) exists when it's rechecked.
Add similar logic to hub over-current changes. (That code is untested,
as those changes do not occur on this laptop.)
