i40e: Fix pre-set max number of queues for VF

commit 8aa55ab422d9d0d825ebfb877702ed661e96e682 upstream.

After setting pre-set combined to 16 queues and reserving 16 queues by
tc qdisc, pre-set maximum combined queues returned to default value
after VF reset being 4 and this generated errors during removing tc.
Fixed by removing clear num_req_queues before reset VF.
