net: ena: fix potential crash when rxfh key is NULL
[ Upstream commit 91a65b7d3ed8450f31ab717a65dcb5f9ceb5ab02 ]
When ethtool -X is called without an hkey, ena_com_fill_hash_function()
is called with key=NULL, which is passed to memcpy causing a crash.
This commit fixes this issue by checking key is not NULL.
Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
