When a BPF gets loaded, it was previously not possible to bind a hid-generic device to hid-multitouch because the group was never updated. This change forces a rescan of the report descriptor after a bpf is loaded/unloaded so we set up the proper group. This was detected while Peter was trying to fix a Viewsonic device: the HID device sending multiotuch data through a proprietary collection was handled by hid-generic, and we don't have any way of attaching it to hid-multitouch because the pre-scanning wasn't able to see the Contact ID HID usage.
