[patch net-next] net: sched: atm: destroy main filter chain

From: Jiri Pirko <redacted>

In atm_tc_destroy, the flow qdisc filter chains are destroyed. However
the main chain is not. So fix this memory and reference leak.

Sending this for net-next because this is present at least from the
beginning of git epoch. Feel free to apply on -net, however I don't have
"Fixes: " :)
