crypto: pcrypt - Fix wrong usage of rcu_dereference()
A kernel with enabled lockdep complains about the wrong usage of
rcu_dereference() under a rcu_read_lock_bh() protected region.
===============================
[ INFO: suspicious RCU usage. ]
3.13.0-rc1+ #126 Not tainted
-------------------------------
linux/crypto/pcrypt.c:81 suspicious rcu_dereference_check() usage!
other info that might help us debug this:
rcu_scheduler_active = 1, debug_locks = 1
1 lock held by cryptomgr_test/153:
#0: (rcu_read_lock_bh){.+....}, at: [<ffffffff812c8075>] pcrypt_do_parallel.isra.2+0x5/0x200
Fix that by using rcu_dereference_bh() instead.
