Fix -verify_return_error in s_client
The "verify_return_error" option in s_client is documented as:
Return verification errors instead of continuing. This will typically
abort the handshake with a fatal error.
In practice this option was ignored unless also accompanied with the
"-verify" option. It's unclear what the original intention was. One fix
could have been to change the documentation to match the actual behaviour.
However it seems unecessarily complex and unexpected that you should need
to have both options. Instead the fix implemented here is make the option
match the documentation so that "-verify" is not also required.
Note that s_server has a similar option where "-verify" (or "-Verify") is
still required. This makes more sense because those options additionally
request a certificate from the client. Without a certificate there is no
possibility of a verification failing, and so "-verify_return_error" doing
nothing seems ok.
Fixes #8079
