[OSS-Tools] [PATCH dt-utils 07/12] barebox-state: remove unused variables

["Ulrich Ölmann" <u.oelmann@pengutronix.de>]

By cleaning up the code the compiler does not emit the following warning
anymore:

    src/barebox-state.c: In function '__state_string_get':
    src/barebox-state.c:254:6: warning: unused variable 'ret' [-Wunused-variable]
      int ret;
          ^~~
    src/barebox-state.c: In function 'state_get':
    src/barebox-state.c:317:25: warning: unused variable 'v' [-Wunused-variable]
      struct state_variable *v;

      const char *backend_type = NULL;
