firmware: arm_scmi: Avoid double free in error flow commit 8305e90a894f82c278c17e51a28459deee78b263 upstream. If device_register() fails, both put_device() and kfree() are called, ending with a double free of the scmi_dev. Calling kfree() is needed only when a failure happens between the allocation of the scmi_dev and its registration, so move it to there and remove it from the error flow.
