Fixed the stack overflow bug in 'battery' console command.stabilize-5784.0.B
On the Nyan EC, we almost run out of the stack of console task.
Instead of making that struct static or global, we print the cached data.
Read the issue tracker for more detailed discussion.
BUG=chrome-os-partner:28027
BRANCH=tot
TEST=verified on nyan with/without battery.
The "battery" console command doesn't crash the system.
