soc: qcom: Fix module cleanup error in dfc

A use after free was observed from qmi_data_ready.
This is due to dfc client freeing the qmi handle before it completes
cleanup. We cannot free the client data in the qmi callback function.
Fix this by making qmi_handle_release return and then free the qmi
handle as it will not be accessed after it.
