soc: qcom: socinfo: fix revision check in qcom_socinfo_probe()
In success case, the revision holds a non-null pointer. The current
logic incorrectly returns an error for a non-null pointer, whereas
it should return an error for a null pointer.
The socinfo driver for IPQ9574 and IPQ5332 is currently broken,
resulting in the following error message
qcom-socinfo qcom-socinfo: probe with driver qcom-socinfo failed with
error -12
Add a null check for the revision to ensure it returns an error only in
failure case (null pointer).
