Summary
gve: Clear napi->skb before dev_kfree_skb_any()
Details

In the Linux kernel, the following vulnerability has been resolved:

gve: Clear napi->skb before devkfreeskb_any()

gverxfreeskb incorrectly leaves napi->skb referencing an skb after it is freed with devkfreeskbany(). This can result in a subsequent call to napigetfrags returning a dangling pointer.

Fix this by clearing napi->skb before the skb is freed.
