x509_rsa_ctx_to_pss returns an error when trying to make an X509_ALGOR
for an arbitrary RSA-PSS salt length. This dates to the initial commit
and isn't in OpenSSL, so I imagine this was an attempt to ratchet down
on RSA-PSS parameter proliferation.
If the caller explicitly passes in md_size, rather than using the -1
convenience value, we currently fail. Allow those too and add an error
to the error queue so it is easier to diagnose.
