bpf: change prototype of bpf_session_{cookie,is_return}

Add the function argument of "void *ctx" to bpf_session_cookie() and
bpf_session_is_return(), which is a preparation of the next patch.

The two kfunc is seldom used now, so it will not introduce much effect
to change their function prototype.
