Log Message:
-----------
bpf: don't return a bogus pointer when gen_bpf_generate() fails
In the case where gen_bpf_generate() fails due to a
_gen_bpf_build_bpf() failure we were returning a pointer to a BPF
program block which we had already freed - oops. Thankfully the
fix is trivial.
Special thanks to Tudor Brindus for not only reporting the problem
but providing a very detailed root cause analysis.
