Fixed bug in edf_higher_prio().prop/robust-tie-break
The rewrite of edf_higher_prio() introduced a bug. When ALL other tie-breaks fail (even PIDs are equal), edf_higher_prio() is supposed to prioritize the task that has an inherited priority. (At least one task must have an inherited priority, due to checks earlier in the function.) However, the rewrite does the inheritance check on the inherited priority (second_task), not the original task (second). This bug can cause G-EDF to fall into an infinite loop in check_for_preemptions() as scheduling decisions thrash.
