perf header: Fix one memory leakage in process_bpf_prog_info()

[ Upstream commit a7da6c7030e1aec32f0a41c7b4fa70ec96042019 ]

Function __perf_env__insert_bpf_prog_info() will return without inserting
bpf prog info node into perf env again due to a duplicate bpf prog info
node insertion, causing the temporary info_linear and info_node memory to
leak. Modify the return type of this function to bool and add a check to
ensure the memory is freed if the function returns false.

Fixes: 606f972b1361f477 ("perf bpf: Save bpf_prog_info information as headers to perf.data")
