ec/ene932: correct ACPI battery data fed into ToString()

Browse Source 
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
