Vulnerability Title
ice: fix Tx scheduler error handling in XDP callback
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
ice: fix Tx scheduler error handling in XDP callback
When the XDP program is loaded, the XDP callback adds new Tx queues.
This means that the callback must update the Tx scheduler with the new
queue number. In the event of a Tx scheduler failure, the XDP callback
should also fail and roll back any changes previously made for XDP
preparation.
The previous implementation had a bug that not all changes made by the
XDP callback were rolled back. This caused the crash with the following
call trace:

Fix this by performing the missing unmapping of XDP queues from
q_vectors and setting the XDP rings pointer back to NULL after all those
queues are released.
Also, add an immediate exit from the XDP callback in case of ring
preparation failure.
