In ixgbevf_get_ringparam we could run into a NULL pointer dereference if the rings were not allocated when we attempted the call. To prevent that we can just access the tx/rx_ring_count values instead of attempting to access the rings to get the count. This change corrects a memory leak and memory corruption in ixgbevf_set_ringparam. The memory leak was due to us not freeing the resources from the ring before overwriting them. This change corrects the memory leak by making certain to call ixgbe_free_tx/rx_resources on the rings prior to freeing them. The memory corruption was because we were replacing the rings but not updating the q_vectors. It addresses the memory corruption by leaving the rings in place and instead just copying the contents of the new rings into the existing rings.
