net/sched: act_mirred: add loop detection
Commit 0f022d32c3ec ("net/sched: Fix mirred deadlock on device recursion")
added code in the fast path, even when act_mirred is not used.
Prepare its revert by implementing loop detection in act_mirred.
Adds an array of device pointers in struct netdev_xmit.
tcf_mirred_is_act_redirect() can detect if the array
already contains the target device.
