interface: unable to to assign tx queue to last worker thread
Using the cli "set interface tx-queue", it is not possible to assign
tx queue to the last worker thread.
The reason is that vdm->first_worker_thread_index is 1. Adding that
to clib_bitmap_last_set (bitmap) exceeds vdm->last_worker_thread_index
when the CLI specifies the last worker thread.
Also make the threads argument optional to enable user to unbind a queue
from any thread.
Type: fix
