Herbert Xu b872f562c8 dm-crypt: Extend state buffer size in crypt_iv_lmk_one
Add a macro CRYPTO_MD5_STATESIZE for the Crypto API export state
size of md5 and use that in dm-crypt instead of relying on the
size of struct md5_state (the latter is currently undergoing a
transition and may shrink).

This commit fixes a crash on 32-bit machines:
