i40evf: check rings before freeing resources
[ Upstream commit fdb47ae87af537b24977a03bc69cfe1c5c55ca62 ]
If the driver gets unloaded during reset recovery, it's possible
that it will attempt to free resources when they're already free.
Add a check to make sure that the Tx and Rx rings actually exist
before dereferencing them to free resources.
