net: ena: rss: fix failure to get indirection table
On old hardware, getting / setting the hash function is not supported while
gettting / setting the indirection table is.
This commit enables us to still show the indirection table on older
hardwares by setting the hash function and key to NULL.
Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
