Subject: [PATCH net 4/6] i40e: Fix pre-set max number of queues for VF

From: Mateusz Palczewski <mateusz.palczewski@...el.com>

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.

Fixes: e284fc280473 (i40e: Add and delete cloud filter)
