perf bpf: Fix metadata leak in perf_env__add_bpf_info() on duplicate insert

When perf_env__insert_bpf_prog_info() returns false (duplicate
program), the error path frees info_linear and info_node but not
info_node->metadata.  If bpf_metadata_create() had succeeded, the
metadata allocation is permanently leaked.

Fix by calling bpf_metadata_free() on info_node->metadata before
freeing info_node.  bpf_metadata_free() handles NULL, so this is
safe even when bpf_metadata_create() returned NULL.
