HID: hid-thrustmaster: fix stack-out-of-bounds read in usb_check_int_endpoints()

Syzbot[1] has detected a stack-out-of-bounds read of the ep_addr array from
hid-thrustmaster driver. This array is passed to usb_check_int_endpoints
function from usb.c core driver, which executes a for loop that iterates
over the elements of the passed array. Not finding a null element at the end of
the array, it tries to read the next, non-existent element, crashing the kernel.

To fix this, a 0 element was added at the end of the array to break the for
loop.

Improper Control of Generation of Code ('Code Injection') 🎯 Medium

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

🛡️ Empfohlene Mitigation: Refactor your program so that you do not have to dynamically generate code.
