ACPI: MRRM: Use for_each_populated_zone() in get_node_num()

Browse Source 
get_node_num() iterates over the populated zones of every online node
with a nested loop. for_each_populated_zone() iterates over the same
zones in the same order.

So use for_each_populated_zone() instead and remove the unused
variable.

No functional change.
