net: sched: cls_fw: add missing tcf_exts_init call in fw_change()
When allocating a new structure we also need to call tcf_exts_init to initialize exts. A follow up patch might be in order to remove some of this code and do tcf_exts_assign(). With this we could remove the tcf_exts_init/tcf_exts_change pattern for some of the classifiers. As part of the future tcf_actions RCU series this will need to be done. For now fix the call here.
