arm64: numa: Don't check node against MAX_NUMNODES
When the NUMA nodes are sorted by checking ACPI SRAT (GICC AFFINITY)
sub-table, it's impossible for acpi_map_pxm_to_node() to return
any value, which is greater than or equal to MAX_NUMNODES. Lets drop
the unnecessary check in acpi_numa_gicc_affinity_init().
No functional change intended.
