Previously, this was AMREX_ALWAYS_ASSERT(ng[dir] >= num_shift);
however, it seems to me that, since num_shift can be negative, we need an absolute value here. What do you think @ax3l ?

Wait, we can shift backwards (or just know it is technically possible because num_shift is an int)? :D
Either way, LGTM ;)

Same as above. This was ng_mw[dir] = num_shift;, but I think that the absolute value is necessary here.
