net_sched: fold tcf_block_cb_call() into tc_setup_cb_call()
After commit 69bd48404f25 ("net/sched: Remove egdev mechanism"),
tc_setup_cb_call() is nearly identical to tcf_block_cb_call(),
so we can just fold tcf_block_cb_call() into tc_setup_cb_call()
and remove its unused parameter 'exts'.
Fixes: 69bd48404f25 ("net/sched: Remove egdev mechanism")
