Ian Rogers 4cd5db4fc4 perf env: Avoid recursively taking env->bpf_progs.lock
[ Upstream commit 9c51f8788b5d4e9f46afbcf563255cfd355690b3 ]

Add variants of perf_env__insert_bpf_prog_info(), perf_env__insert_btf()
and perf_env__find_btf prefixed with __ to indicate the
env->bpf_progs.lock is assumed held.

Call these variants when the lock is held to avoid recursively taking it
and potentially having a thread deadlock with itself.

Fixes: f8dfeae009 ("perf bpf: Show more BPF program info in print_bpf_prog_info()")
