Sewon Nam c487fcc632 bpf: bpftool: Setting error code in do_loader()
[ Upstream commit 02a4694107b4c830d4bd6d194e98b3ac0bc86f29 ]

We are missing setting error code in do_loader() when
bpf_object__open_file() fails. This means the command's exit status code
will be successful, even though the operation failed. So make sure to
return the correct error code. To maintain consistency with other
locations where bpf_object__open_file() is called, return -1.
