HID: wiimote: Fix IR data parser

commit 74b89e8a3625c17c7452532dfb997ac4f1a38751 upstream.

We incorrectly parse incoming IR data. The extra byte contains the upper
bits and not the lower bits of the x/y coordinates. User-space expects
absolute position data from us so this patch does not break existing
applications. On the contrary, it extends the virtual view and fixes
garbage reports for margin areas of the virtual screen.
