before this change, we cannot pass a `const struct option*` to
spdk_app_parse_args() even the callee does not mutate the value pointed
by the pointer. in other words, we are not able to write something like:
static const option g_options[] = {...};
// ...
spdk_app_parse_args(argc, argv, &opts, "",
g_options, app_parse_arg, app_usage);
after this change, the requirement of the type of the `option` argument
is relaxed, so we can pass a `const struct option*` to this function
now.
