From: David Vrabel <david.vrabel@xxxxxxxxxx> commit 4a658527271bce43afb1cf4feec89afe6716ca59 upstream. When xenvif_connect() fails it may leave a stale NAPI instance added to the device. Make sure we delete it in the error path. Signed-off-by: David Vrabel <david.vrabel@xxxxxxxxxx> Signed-off-by: David S.
