net/mlx5e: add missing cpu_to_node to kvzalloc_node in mlx5e_open_xdpredirect_sq
In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: add missing cpu_to_node to kvzalloc_node in mlx5e_open_xdpredirect_sq

kvzalloc_node is not doing a runtime check on the node argument
(__alloc_pages_node_noprof does have a VM_BUG_ON, but it expands to
nothing on !CONFIG_DEBUG_VM builds), so doing any ethtool/netlink
operation that calls mlx5e_open on a CPU that's larger that MAX_NUMNODES
triggers OOB access and panic (see the trace below).

Add missing cpu_to_node call to convert cpu id to node id.
