Subject: net: sched: fix tcf_block_get_ext() in case CONFIG_NET_CLS is not set
Patch-mainline: v4.16-rc1
Git-commit: 33c30a8b68cf837b2be3e885ae0a329b880d7666
References: bsc#1109837

The definition of functions tcf_block_get() and tcf_block_get_ext()
depends of CONFIG_NET_CLS being set. When those functions gained extack
support, only one version of the declaration of those functions was
updated. Function tcf_block_get() was later fixed with commit
3c1490913f3b ("net: sch: api: fix tcf_block_get").

Change arguments of tcf_block_get_ext() for the case when CONFIG_NET_CLS
is not set.

Fixes: 8d1a77f974ca ("net: sch: api: add extack support in tcf_block_get")
