clk: qcom: Return correct error code in qcom_cc_probe_by_index()

When devm_platform_ioremap_resource() fails, it returns various
error codes. Returning a hardcoded -ENOMEM masks the actual
failure reason.

Use PTR_ERR() to propagate the actual error code returned by
devm_platform_ioremap_resource() instead of -ENOMEM.
