The return value could be NULL if the casting is illegal.
A new helper return type RET_PTR_TO_BTF_ID_OR_N

Hi Yonghong,
I love your patch! Yet something to improve:

The helper is used in tracing programs to cast a socket
pointer to a tcp6_sock pointer.
The return value could be NULL if the casting is illegal.
A new helper return type RET_PTR_TO_BTF_ID_OR_NULL is added
so the verifier is able to deduce proper return types for the helper.
Different from the pr
