ec/ene_kb3940q: correct ACPI battery data fed into ToString()
ToString() requires the input buffer data to be null-terminated,
but the data returned by the EC is not, leading Windows to fail
to report any battery data at all. Correct this by concatenating
a null terminator (0x00) to the end of the buffer data before
inputting to ToString() where needed
TEST: boot Windows on google/butterfly, observe battery data
reported correctly.
