Restore handling of the third argument (id) of hid_start_parse(), same as
it is done in NetBSD/OpenBSD, and as it was here before r205728.
I personally think this API or its implementation is incorrect, as it is not
correct to filter collections based on report ID, as they are orthogonal
in general case, but I see no harm from supporting this feature.
