Subject: [PATCH 5.4 116/129] dm crypt: Initialize crypto wait structures

From: Damien Le Moal <damien.lemoal@....com>

commit 7785a9e4c228db6d01086a52d5685cd7336a08b7 upstream.

Use the DECLARE_CRYPTO_WAIT() macro to properly initialize the crypto
wait structures declared on stack before their use with
crypto_wait_req().

Fixes: 39d13a1ac41d ("dm crypt: reuse eboiv skcipher for IV generation")
Fixes: bbb1658461ac ("dm crypt: Implement Elephant diffuser for Bitlocker compatibility")
