kernel - dm - Reorganize the crypt code and implement B_HASBOGUS
* Implement B_HASBOGUS data copying for read decryption. When a buffer
contains bogus pages we may or may not be able to safely decrypt data
in-place, add some code to deal with it.
* Reorganize the crypt code. Separate the read and write paths and
organize the procedures in the same order as the execution stages.
Also move some of the buffer manipulation around a little to make
it more clear.
