hwmon: (asus-ec-sensors) check sensor index in read_string()
Prevent a potential invalid memory access when the requested sensor
is not found.
find_ec_sensor_index() may return a negative value (e.g. -ENOENT),
but its result was used without checking, which could lead to
undefined behavior when passed to get_sensor_info().
Add a proper check to return -EINVAL if sensor_index is negative.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: d0ddfd241e57 ("hwmon: (asus-ec-sensors) add driver for ASUS EC")
