HID: bigben: fix slab-out-of-bounds Write in bigben_probe
There is a slab-out-of-bounds Write bug in hid-bigbenff driver.
The problem is the driver assumes the device must have an input but
some malicious devices violate this assumption.
Fix this by checking hid_device's input is non-empty before its usage.
