Fix bug in get_battery_level() where we attempt to apply hysteresis
to the battery percentage when it jumps between levels. The problem
is if the battery jumps up multiple levels, then it won't always
update the battery level. For example, using level thresholds of
{14, 40, 99}, if you jump from 0% to 99%, it won't update the battery
level because it compares the new percentage, 99%, with the
battery threshold for the new level + 1 (100%).
BUG=chrome-os-partner:45878
BRANCH=smaug
TEST=use the battfake console command to jump from 5% to 99% and
verify that the lightbar goes from all red to google colors. note:
without this CL, the lightbar stays all red.
