Fix leaks on error in PKINIT signed-data creation
In cms_signeddata_create(), free more allocated variables in the
cleanup label to prevent them from leaking on error paths. Also check
the result of X509_STORE_CTX_get1_chain() before using it, to prevent
a null dereference on allocation failure. Reported by Brian Knoll.
