[PATCH] crypto: doc - Fix hash export state information

[Rabin Vincent <rabin.vincent@axis.com>]

From: Rabin Vincent <rabinv@axis.com>

The documentation states that crypto_ahash_reqsize() provides the size
of the state structure used by crypto_ahash_export().  But it's actually
crypto_ahash_statesize() which provides this size.
