Cleanly force battery to mAh mode when reading capacity
Smart batteries can report capacity in mAh or 10mW units. We forced
the units to mAh in charge_state.c's main loop, but that doesn't
guarantee that they're actually set before the capacity is read. It's
cleaner to check the capacity reporting mode when actually reading the
capacity.
BUG=chrome-os-partner:20881
BRANCH=none
TEST=battery command reports the same capacity data before/after change
(on rambi, design=2940 mAh)
