wifi: iwlwifi: fix aux ROC time event iterator usage
The list_for_each_entry() iterator must not be used outside the loop.
Even though we break and check for NULL, doing so still violates kernel
iteration rules and triggers Coccinelle's use_after_iter.cocci warning.
Cache the matched entry in aux_roc_te and use it consistently after the
loop. This follows iterator best practices, resolves the warning, and
makes the code more maintainable.
