url: remove arg value check from CURLOPT_SSH_AUTH_TYPES

Since CURLSSH_AUTH_ANY (aka CURLSSH_AUTH_DEFAULT) is ~0 an arg value
check on this option is incorrect; we have to accept any value.

Prior to this change since f121575 (7.56.1+) CURLOPT_SSH_AUTH_TYPES
erroneously rejected CURLSSH_AUTH_ANY with CURLE_BAD_FUNCTION_ARGUMENT.
