[Patch 4.14 0/4] net_sched: backport tc filter fixes to 4.14

This patchset backports 4 important bug fixes for tc filter to
4.14 stable branch. Due to some big changes between 4.14 and 4.15,
the backports are not trivial, I have to adjust and fix the conflicts
manually.

Thanks to Roland for reporting the kernel warning and testing
the patches.
