commit 1c5d4221240a233df2440fe75c881465cdf8da07 upstream.
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).
