Update dream battery drain monitoring to exclude when charging is being

artificially limited.

We may limit charging when battery is overheating, or due to dock defend
or other battery defend mechanisms. In these cases, the battery is
expected to drain while dreaming since charging is limited. Therefore,
do not exit dreams in this case.
