net/sched: cls_api: Move call to tcf_exts_miss_cookie_base_destroy()
When CONFIG_NET_CLS_ACT is disabled:
../net/sched/cls_api.c:141:13: warning: 'tcf_exts_miss_cookie_base_destroy' defined but not used [-Wunused-function]
141 | static void tcf_exts_miss_cookie_base_destroy(struct tcf_exts *exts)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Due to the way the code is structured, it is possible for a definition
of tcf_exts_miss_cookie_base_destroy() to be present without actually
being used. Its single callsite is in an '#ifdef CONFIG_NET_CLS_ACT'
block but a definition will always be present in the file. The version
of tcf_exts_miss_cookie_base_destroy() that actually does something
depends on CONFIG_NET_TC_SKB_EXT, so the stub function is used in both
CONFIG_NET_CLS_ACT=n and CONFIG_NET_CLS_ACT=y + CONFIG_NET_TC_SKB_EXT=n
configurations.
Move the call to tcf_exts_miss_cookie_base_destroy() in
tcf_exts_destroy() out of the '#ifdef CONFIG_NET_CLS_ACT', so that it
always appears used to the compiler, while not changing any behavior
with any of the various configuration combinations.
