perf bpf: Fix two memory leakages when calling perf_env__insert_bpf_prog_info()

[ Upstream commit 03edb702 ]

If perf_env__insert_bpf_prog_info() returns false due to a duplicate bpf
prog info node insertion, the temporary info_node and info_linear memory
will leak. Add a check to ensure the memory is freed if the function
returns false.

Fixes: d56354dc ("perf tools: Save bpf_prog_info and BTF of new BPF programs")
