HTTP: fix empty-body warning

This change fixes a compiler warning with gcc-12.2.0 when
`-DCURL_DISABLE_BEARER_AUTH=ON` is used.

    /home/tox/src/curl/lib/http.c: In function 'Curl_http_input_auth':
    /home/tox/src/curl/lib/http.c:1147:12: warning: suggest braces around empty body in an 'else' statement [-Wempty-body]
     1147 |            ;
          |            ^

Closes #12262
