net/qede: fix VF RSS configuration

The newer SR-IOV PF drivers expects RX/TX queues to be created before
applying RSS configuration. This patch addresses this requirement by
deferring RSS configuration till the queues are created. Even though
this issue is only seen in SR-IOV context, the changes will be made
applicable to PF also to keep the behavior consistent between VF/PF.
