dm crypt: Initialize crypto wait structures

Use the DECLARE_CRYPTO_WAIT() macro to properly initialize the crypto wait structures declared on stack before their use with crypto_wait_req(). Fixes: 39d13a1 ("dm crypt: reuse eboiv skcipher for IV generation") Fixes: bbb1658 ("dm crypt: Implement Elephant diffuser for Bitlocker compatibility") Cc: [email protected] Signed-off-by: Damien Le Moal <[email protected]> Signed-off-by: Mike Snitzer <[email protected]>
