Fix return value of the i2d_ASN1_bio_stream() call

If the flags argument does not contain the SMIME_STREAM bit,
the i2d_ASN1_bio_stream() function always returns 1,
ignoring the result of the ASN1_item_i2d_bio() call.

Fix the return value to the result of the ASN1_item_i2d_bio()
call for this case.
