cms encrypt, better OBJ_nid2obj() return check
Fixes #22225
In OBJ_nid2obj(), if the NID does not have an OID, then a pointer to
the special "undefined" ASN1_OBJECT is returned. Check for the
undefined-ASN1_OBJECT and return an error. Also, add a test for this
in 80-test_cms.t.
Testing:
#!/bin/bash -x
shopt -s expand_aliases
alias openssl="LD_LIBRARY_PATH=~/git/openssl ~/git/openssl/apps/openssl"
echo "This is a confidential message. It should be encrypted." > msg.txt
## this should fail b/c there is no OID for aes-256-ctr
openssl cms -encrypt -in msg.txt -aes-256-ctr -out msg.txt.cms -recip demos/cms/signer.pem
echo $?
