i40evf: don't configure unused RSS queues 

The driver will only configure as many queues as there are available
CPUs, up the maximum number of queues. However, it always configures
RSS as though it is using the maximum number of queues. This can cause
the device to drop a lot of RX traffic, as the packets get assigned to
nonfunctional queues.

Fix this by only configuring RSS with the number of active queues.
