[kernel] swconfig: Check vlan/port indexes for validity.

Swconfig needs to make sure that requested vlans/ports actually exist,
else it might read or modify memory not belonging to itself.

This patch adds a quick range check in swconfig's kernel part to
prevent accidential or intentional memory modification.
