cifs: fix double free on failed kerberos auth
commit 39e8db3c860e2678ce5a7d74193925876507c9eb upstream.
If session setup failed with kerberos auth, we ended up freeing
cifs_ses::auth_key.response twice in SMB2_auth_kerberos() and
sesInfoFree().
Fix this by zeroing out cifs_ses::auth_key.response after freeing it
in SMB2_auth_kerberos().
Fixes: a4e430c8c8ba ("cifs: replace kfree() with kfree_sensitive() for sensitive data")
