Hangyu Hua 3cc54473ba net: sched: fix possible refcount leak in tc_chain_tmplt_add() 
[ Upstream commit 44f8baaf230c655c249467ca415b570deca8df77 ]

try_module_get will be called in tcf_proto_lookup_ops. So module_put needs
to be called to drop the refcount if ops don't implement the required
function.

Fixes: 9f407f1768d3 ("net: sched: introduce chain templates")
