Subject: net: sched: use newly added classid identity helpers
Patch-mainline: v4.14-rc1
Git-commit: a2e8da9378cc09e2e922a0b3d481bd9d07c3d245
References: bsc#1056787

Instead of checking handle, which does not have the inner class
information and drivers wrongly assume clsact->egress as ingress, use
the newly introduced classid identification helpers.
