Subject: sch_dsmark: Fix uninitialized variable warning.
Patch-mainline: v4.13-rc1
Git-commit: 9d4f97f97bb8adc47f569d995402c33de9a4fa19
References: bsc#1056787

We still need to initialize err to -EINVAL for
the case where 'opt' is NULL in dsmark_init().

Fixes: 6529eaba33f0 ("net: sched: introduce tcf block infractructure")
