[PATCH 2/3] crypto: spacc - Fix NULL vs IS_ERR() check in spacc_aead_fallback()

[Dan Carpenter <dan.carpenter@linaro.org>]

The crypto_alloc_aead() function doesn't return NULL pointers, it returns
error pointers.  Fix the error checking.

Fixes: 06af76b46c78 ("crypto: spacc - Add SPAcc aead support")
