staging: nvec: Fix incorrect null termination of battery manufacturer

[ Upstream commit a8934352ba01081c51d2df428e9d540aae0e88b5 ]

The battery manufacturer string was incorrectly null terminated using
bat_model instead of bat_manu. This could result in an unintended
write to the wrong field and potentially incorrect behavior.

fixe the issue by correctly null terminating the bat_manu string.
