net_sched: reject unknown tcfa_action values
After the commit 802bfb19152c ("net/sched: user-space can't set
unknown tcfa_action values"), unknown tcfa_action values are
converted to TC_ACT_UNSPEC, but the common agreement is instead
rejecting such configurations.
This change also introduces a helper to simplify the destruction
of a single action, avoiding code duplication.
v1 -> v2:
- helper is now static and renamed according to act_* convention
- updated extack message, according to the new behavior
Fixes: 802bfb19152c ("net/sched: user-space can't set unknown tcfa_action values")
