Sudeep Holla c09880cef7 hwmon: (scmi) return -EINVAL when sensor information is unavailable ...

Passing NULL pointer to PTR_ERR will result in return value of 0
indicating success which is clearly not what it is intended here.

This patch returns -EINVAL instead when the sensor information is not
available.
