hwmon: (cros_ec) Prevent read overflow in probe()

The "resp.sensor_name" comes from cros_ec_cmd() and it hasn't necessarily
been NUL terminated.  We had not intended to read past "sensor_name_size"
bytes, however, there is a width vs precision bug in the format string.
The format needs to be precision '%.*s' instead of width '%*s'.
Precision prevents an out of bounds read, but width is a no-op.
