[BATTC] Fix the wait timeout conversion

Browse Source 
KeWaitForSingleObject takes 100ns unit for timeout. Both IOCTL_BATTERY_QUERY_TAG and IOCTL_BATTERY_QUERY_STATUS take a wait for the timeout in milliseconds.
Supposedly a miniport driver wants to supply a wait of 5000 ms (which is equivalent to 5 s), the miniport driver WON'T BE WAITING 5 seconds but 0.5!!!
