Johannes Berg 96a94cc515 bpf: reference may_access_skb() from __bpf_prog_run() ...

It took me quite some time to figure out how this was linked,
so in order to save the next person the effort of finding it
add a comment in __bpf_prog_run() that indicates what exactly
determines that a program can access the ctx == skb.
