crypto/pcrypt: Replace synchronize_rcu_bh() with synchronize_rcu()
Now that synchronize_rcu() waits for bh-disable regions of code as well as RCU read-side critical sections, the synchronize_rcu_bh() in pcrypt_cpumask_change_notify() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E.
