crypto: shash - remove pointless checks of shash_alg::{export,import}
crypto_init_shash_ops_async() only gives the ahash tfm non-NULL
->export() and ->import() if the underlying shash alg has these
non-NULL. This doesn't make sense because when an shash algorithm is
registered, shash_prepare_alg() sets a default ->export() and ->import()
if the implementor didn't provide them. And elsewhere it's assumed that
all shash algs and ahash tfms have non-NULL ->export() and ->import().
Therefore, remove these unnecessary, always-true conditions.
