commit 57f97834efe0c208ffadc9d2959f3d3d55580e52 cleaned up the cac_applet_pki_process_apdu function to have a single exit point. Unfortunately, that commit introduced a bug where the sign buffer can get free'd and nullified while it's still being used. This commit corrects the bug by introducing a boolean to track whether or not the sign buffer should be freed in the function exit path.
