block: Allow t10-pi to be modular
Currently t10-pi can only be built into the block layer which via crc-t10dif pulls in a whole chunk of the Crypto API. In fact all users of t10-pi work as modules and there is no reason for it to always be built-in. This patch adds a new hidden option for t10-pi that is selected automatically based on BLK_DEV_INTEGRITY and whether the users of t10-pi are built-in or not.
