Revert "HID: magicmouse: ignore 'ivalid report id' while switching modes" 

This reverts commit 23746a66d7.

It turned out that the actual reason for failure is not the device
firmware, but bug in Bluetooth stack, which will be fixed by
patch by Ville Tervo which corrects the mask handling for CSR 1.1
Dongles.
