qemu-option: Check return value instead of @err where convenient
Convert uses like
opts = qemu_opts_create(..., &err);
if (err) {
...
}
to
opts = qemu_opts_create(..., errp);
if (!opts) {
...
}
Eliminate error_propagate() that are now unnecessary. Delete @err
that are now unused.
Note that we can't drop parallels_open()'s error_propagate() here. We
continue to execute it even in the converted case. It's a no-op then:
local_err is null.
