bpf: clear list node owner and unlink before drop

When draining a BPF list_head, this commit ensures each node's owner
pointer is cleared while holding the spinlock and delinks each node before
calling __bpf_obj_drop_impl() to prevent invalid next node references.

This commit appears to fix a bug but is missing a Fixes: tag. The issue
being addressed traces back to the introduction of bpf_list_head support in
map values. Should this commit include:

Fixes: f0c5941ff5b2 ("bpf: Support bpf_list_head in map values")
