net: ncsi: Fix buffer overflow in fetching version id

[ Upstream commit 8e16170a ]

In NC-SI spec v1.2 section 8.4.44.2, the firmware name doesn't
need to be null terminated while its size occupies the full size
of the field. Fix the buffer overflow issue by adding one
additional byte for null terminator.
