fix a bug of calculate_min_atomic_distance function

[BBBuZHIDAO]

Summary

Function calculate_min_atomic_distance (#890 ) will not update min_n1 if all distances are larger than dist_sq. So there may be a memory error for many systems when reading the -1th atomic symbol from array cpu_atom_symbol.

Modification

Check min_n1 before print and use macro to set the limit of minimum distance

Others

I tested in $\mathrm{MoS_2}$. This function may need more other tests.
