rcu: Fix misprint in srcu_funnel_exp_start
The srcu_funnel_exp_start() function checks to see if the srcu_struct structure's expedited grace period counter needs updating to reflect a newly arrived request for an expedited SRCU grace period. Unfortunately, the check is backwards, so this commit reverses the sense of the test. Signed-off-by: Ildar Ismagilov <devix84@gmail.com> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
