By default main RSS table should change to include all queues.
When user sets a specific RSS config the driver should preserve it,
even when queue count changes. Driver should refuse to deactivate
queues used in the user-set RSS config.
For additional contexts driver should still refuse to deactivate
queues in use. Whether the contexts should get resized like
context 0 when queue count increases is a bit unclear. I anticipate
most drivers today don't do that. Since main use case for additional
contexts is to set the indir table - it doesn't seem worthwhile to
care about behavior of the default table too much. Don't test that.
