Subject: [PATCH 44/48] rcutorture: Removing redundant function pointer initialization

From: Zqiang <qiang.zhang1211@...il.com>

For these rcu_torture_ops structure's objects defined by using static,
if the value of the function pointer in its member is not set, the default
value will be NULL, this commit therefore remove the pre-existing
initialization of function pointers to NULL.
