libcacard: don't free sign buffer while sign op is pending

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.
