Zichen Xie bcba86e03b netdevsim: Add trailing zero to terminate the string in nsim_nexthop_bucket_activity_write() 
[ Upstream commit 4ce1f56a1e ]

This was found by a static analyzer.
We should not forget the trailing zero after copy_from_user()
if we will further do some string operations, sscanf() in this
case. Adding a trailing zero will ensure that the function
performs properly.
