[ Upstream commit 12c331b29c7397ac3b03584e12902990693bc248 ]
gve_alloc_pending_packet() can return NULL, but gve_tx_add_skb_dqo()
did not check for this case before dereferencing the returned pointer.
Add a missing NULL check to prevent a potential NULL pointer
dereference when allocation fails.
This improves robustness in low-memory scenarios.
Fixes: a57e5de476 ("gve: DQO: Add TX path")
