hv_netvsc: defer queue selection to VF

[ Commit b3bf5666a51068ad5ddd89a76ed877101ef3bc16 upstream. ]

When VF is used for accelerated networking it will likely have
more queues (and different policy) than the synthetic NIC.
This patch defers the queue policy to the VF so that all the
queues can be used. This impacts workloads like local generate UDP.
