ec/ene932: 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
