exec.c: get nodes_nb_alloc with one MAX calculation
The purpose of these two MAX here is to get the maximum of these three
variables:
A: map->nodes_nb + nodes
B: map->nodes_nb_alloc
C: alloc_hint
We can write it like MAX(A, B, C). Since the if condition says A > B,
this means MAX(A, B, C) = MAX(A, C).
This patch just simplify the calculation a bit.
