dm crypt: restructure essiv error path

commit 5861f1be00b3b70f8ab5e5a81392a6cf69666cd2 upstream.

Use kzfree for salt deallocation because it is derived from the volume
key.  Use a common error path in ESSIV constructor.

Required by a later patch which fixes the way key material is wiped
from memory.
