rcutorture: Enable limited callback-flooding tests of SRCU
This commit allows up to 50,000 callbacks worth of callback-flooding tests of SRCU. The goal of this change is to exercise Tree SRCU's ability to transition from SRCU_SIZE_SMALL to SRCU_SIZE_BIG triggered by callback-queue-time lock contention. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
