Merge branch 'act_pedit-minor-improvements'

Pedro Tammela says:

====================
net/sched: act_pedit: minor improvements

This series aims to improve the code and usability of act_pedit for
netlink users.

Patches 1-2 improves error reporting for extended keys parsing with extack.

Patch 3 checks the static offsets a priori on create/update. Currently,
this is done at the datapath for both static and runtime offsets.

Patch 4 removes a check from the datapath which is redundant since the
netlink parsing validates the key types.

Patch 5 changes the 'pr_info()' calls in the datapath to rate limited
versions.
