net: veth: Page pool creation error handling for existing pools only

Browse source

[ Upstream commit 8a519a5725 ]

The failure handling procedure destroys page pools for all queues,
including those that haven't had their page pool created yet. this patch
introduces necessary adjustments to prevent potential risks and
inconsistency with the error handling behavior.
