net/sched: cls_api: Initialize miss_cookie_node when action miss is not used
Function tcf_exts_init_ex() sets exts->miss_cookie_node ptr only
when use_action_miss is true so it assumes in other case that
the field is set to NULL by the caller. If not then the field
contains garbage and subsequent tcf_exts_destroy() call results
in a crash.
Ensure that the field .miss_cookie_node pointer is NULL when
use_action_miss parameter is false to avoid this potential scenario.
Fixes: 80cd22c35c90 ("net/sched: cls_api: Support hardware miss to tc action")
