[PATCH net 3/3] sch_cake: fix a few style nits

[Toke Høiland-Jørgensen]

From: Toke Høiland-Jørgensen <t...@redhat.com>

I spotted a few nits when comparing the in-tree version of sch_cake with
the out-of-tree one: A redundant error variable declaration shadowing an
outer declaration, and an indentation alignment issue. Fix both of these.

Fixes: 046f6fd5daef ("sched: Add Common Applications Kept Enhanced (cake) 
qdisc")
