From: "Paul E. McKenney" <paul...@linux.vnet.ibm.com>
The srcu_torture_stats() function prints SRCU's per-CPU c[] array with
an unsigned format, which means that the number one less than zero is
a very large number. This commit therefore prints this array with a
signed format in order to improve readability of the rcutorture output.
