HID: uhid: Over-ride the default maximum data buffer value with our own

The default maximum data buffer size for this interface is UHID_DATA_MAX
(4k).  When data buffers are being processed, ensure this value is used
when ensuring the sanity, rather than a value between the user provided
value and HID_MAX_BUFFER_SIZE (16k).
