Commit 7fb09a737536 ("ice: Modify recursive way of adding nodes")
changed ice_sched_add_nodes_to_layer() from recursive control flow to an
iterative loop.

Inside the loop, first_teid_ptr may be set to the address of a
block-local variable:

	u32 temp;
	...
	if (num_added)
		first_teid_ptr = &temp;

On the next loop iteration, first_teid_ptr may be passed to
ice_sched_add_nodes_to_hw_layer(), after temp from the previous
iteration has gone out of scope.

Move temp outside the loop so the pointer remains valid for the lifetime
of ice_sched_add_nodes_to_layer().

This was found by Clang with LifetimeSafety enabled while testing C
language support on a Linux allmodconfig build.
