crypto: pcrypt - Fix user-after-free on module unload
commit b61ad212689fc7ef61f32112a0ffddfcbc8a6159 upstream.
On module unload of pcrypt we must unregister the crypto algorithms
first and then tear down the padata structure. As otherwise the
crypto algorithms are still alive and can be used while the padata
structure is being freed.
