rootless: Add a note for disabling vhost-net config

Add a note about degraded performance with disabling vhost-net. Also, this is something that should be handled by the code in the future. We should typically try to minimise any extra setup steps required for rootless and try to work towards having this work out of the box. Signed-off-by: Archana Shinde <[email protected]>

+no longer be required as Kata runtime should handle this automatically for rootless case.
+This does mean you will get slightly degraded network performance.
