net: mvneta: Fix for_each_present_cpu usage

commit 129219e4950a3fcf9323b3bbd8b224c7aa873985 upstream.

This patch convert the for_each_present in on_each_cpu, instead of
applying on the present cpus it will be applied only on the online cpus.
This fix a bug reported on
http://thread.gmane.org/gmane.linux.ports.arm.kernel/468173.

Using the macro on_each_cpu (instead of a for_each_* loop) also ensures
that all the calls will be done all at once.
