crypto: inside-secure - fix zeroing of the request in ahash_exit_inv

[ Upstream commit b926213d6fede9c9427d7c12eaf7d9f0895deb4e ]

A request is zeroed in safexcel_ahash_exit_inv(). This request total
size is EIP197_AHASH_REQ_SIZE while the memset zeroing it uses
sizeof(struct ahash_request), which happens to be less than
EIP197_AHASH_REQ_SIZE. This patch fixes it.
