HID: logitech-dj: validate output report details
commit 297502abb32e225fb23801fcdb0e4f6f8e17099a upstream.
A HID device could send a malicious output report that would cause the
logitech-dj HID driver to leak kernel memory contents to the device, or
trigger a NULL dereference during initialization:
