    Add missing brackets to multi-statement if in SaveServerAuthorizations
    
    Introduced by commit 5222d28e8d8e5b4cc
    
    Reported by gcc 7.3:
    
    auth.c: In function ‘SaveServerAuthorizations’:
    auth.c:447:6: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
          if (auths[i]->data_length > 0)
          ^~
    auth.c:452:3: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
       (void) fflush (auth_file);
       ^
