HID: steam: Zero-initialize reply in serial lookup

Browse source

When requesting the serial number from a controller, the function will do
some basic bounds checking to make sure the reply is valid, as well as
capping off the reply with a null byte before copying. However, the error
logging can leak uninitialized memory in some cases. We can simplify and
solve this by just zero-initalizing the reply memory eagerly instead.
