HID: sony: validate HID output report details

This driver must validate the availability of the HID output report and
its size before it can write LED states via buzz_set_leds(). This stops
a heap overflow that is possible if a device provides a malicious HID
output report:

[  108.171280] usb 1-1: New USB device found, idVendor=054c, idProduct=0002
...
[  117.507877] BUG kmalloc-192 (Not tainted): Redzone overwritten

CVE-2013-2890
