Gilles Peskine 570a8cd056 Fix null pointer arithmetic in error case 
When mbedtls_nist_kw_wrap was called with output=NULL and out_size=0, it
performed arithmetic on the null pointer before detecting that the output
buffer is too small and returning an error code. This was unlikely to have
consequences on real-world hardware today, but it is undefined behavior and
UBSan with Clang 10 flagged it. So fix it (fix #4025).

Fix a similar-looking pattern in unwrap, though I haven't verified that it's
reachable there.
