  REGRESSION: CMS_final: do not ignore CMS_dataFinal result

The CMS_dataFinal result is important as signature may fail, however, it
is ignored while returning success from CMS_final.

The SMIME_crlf_copy result is returned while it is ignored in the rest
of the openssl code.

Prefer the CMS_dataFinal result.

This is regression from openssl-1.

Blame finds c1669f41ei as root cause of regression.

  Handle SMIME_crlf_copy return code

Currently the SMIME_crlf_copy result is ignored in all usages. It does
return failure when memory allocation fails.

This patch handles the SMIME_crlf_copy return code in all occurrences.
