act_mirred is not a driver, apparently.

Real question is more like : what is the impact of propagating an error
at this point ?

_If_ we are going to just propagate the error like egress, then
the difference is m->tcf_action (PIPE or STOLEN) vs TC_ACT_SHOT.
And this error code is propagated from tcf_action_exec() up to
qdisc layer...
