    Fix unused variable warning in mlx5_fs_tree.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/dev/mlx5/mlx5_core/mlx5_fs_tree.c:1408:15: error: variable 'candidate_group_num' set but not used [-Werror,-Wunused-but-set-variable]
                unsigned int candidate_group_num = 0;
                             ^
    
    The 'candidate_group_num' variable appears to have been a debugging aid
    that has never been used for anything, so remove it.
    
    MFC after:      3 days
    
    (cherry picked from commit 6332ad8673fb108dcb8af0aaa42d75ea845748d7)
