Revert "MTU: Setting of MTU on software interface (instead of hardware interface)"

This reverts commit 70083ee74c3141bbefb185525315f1b34497dcaa.

Reverting as this patch is causing following crash:

0: /home/damarion/cisco/vpp3/build-data/../src/vnet/devices/devices.h:131 (vnet_get_device_input_thread_index) assertion `queue_id < vec_len (hw->input_node_thread_index_by_queue)' fails
