crypto/pcrypt: Replace synchronize_rcu_bh() with synchronize_rcu()

Browse Source 
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.
