bpf: refactor __bpf_list_del to take list node pointer

Browse source

Refactor __bpf_list_del to accept (head, struct list_head *n) instead of
(head, bool tail). The caller now passes the specific node to remove:
bpf_list_pop_front passes h->next, bpf_list_pop_back passes h->prev.

Prepares for introducing bpf_list_del(head, node) kfunc to remove an
arbitrary node when the user holds ownership.
