tools: bpftool: remove duplicated error message on prog load
do_pin_fd() will already print out an error message if something
goes wrong. Printing another error is unnecessary and will break
JSON output, since error messages are full objects:
$ bpftool -jp prog load tracex1_kern.o /sys/fs/bpf/a
{
"error": "can't pin the object (/sys/fs/bpf/a): File exists"
},{
"error": "failed to pin program"
}
Fixes: 49a086c201a9 ("bpftool: implement prog load command")
