Milan Broz dd3fe9f5fd Check cipher before LUKS conversion to LUKS2. ...

There are some historic incompatibilities that are ignored
for LUKS1 but do not work for LUKS2.

Check the cipher before conversion through crypto backend.

Also it switches LUKS2_check_cipher to use userspace backend only
(this should be ok for the reencryption code that uses it too).

Fixes: #641
