can: peak_usb: fix slab info leak
commit f7a1337f0d29b98733c8824e165fca3371d7d4fd upstream.
Fix a small slab info leak due to a failure to clear the command buffer
at allocation.
The first 16 bytes of the command buffer are always sent to the device
in pcan_usb_send_cmd() even though only the first two may have been
initialised in case no argument payload is provided (e.g. when waiting
for a response).
Fixes: bb4785551f64 ("can: usb: PEAK-System Technik USB adapters driver core")
