Abort with a clear message if either local tile dimension is too small to
hold the halo cells the chosen reconstruction scheme requires. Mirrors the
1D validate_decomp; called from the 2D driver right after the
decomposition is built (an over-fine MPI process grid, e.g. a thin axis
from MPI_Dims_create, would otherwise silently over-read halos).
