Fix for benign UBsan signed-integer-overflow complaints.
...
When counting nl and nc, the nnz is optionally also counted when in sparse mode. However, the functions mj_nl and mj_nc unconditionally counts nnz into a temporary accumulator, then only afterwards check whether the output nnz pointer is NULL.
When not in sparse mode, ten_J_rownnz does not get initialized by mj_tendon, however mj_nl and mj_nc are accumulating potentially spurious data from ten_J_rownnz into the temporary accumulator. While the spurious result eventually gets discarded, UBsan nevertheless detects an integer overflow in the temporary accumulator.
