rcu: Protect rcu_check_gp_kthread_starvation() access to ->gp_flags

Browse source

The rcu_check_gp_kthread_starvation() function can be invoked without
holding locks, so the access to the rcu_state structure's ->gp_flags
field must be protected with READ_ONCE().  This commit therefore adds
this protection.
