bpf: Ensure RCU lock is held around bpf_prog_ksym_find
Add a warning to ensure RCU lock is held around tree lookup, and then
fix one of the invocations in bpf_stack_walker. The program has an
active stack frame and won't disappear. Use the opportunity to remove
unneeded invocation of is_bpf_text_address.
Fixes: f18b03fabaa9 ("bpf: Implement BPF exceptions")
