rcutorture: Remove redundant initialization to zero
The current code initializes the global per-CPU variables rcu_torture_count and rcu_torture_batch to zero. However, C does this initialization by default, and explicit initialization of per-CPU variables now needs a different syntax if "make tags" is to work. This commit therefore removes the initialization. Reported-by: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
