crypto: keembay - Fix AEAD unregister count in error path

Browse source

register_aes_algs() registers the AEAD algorithms before registering the
skcipher algorithms.  If skcipher registration fails, the function unwinds
the earlier AEAD registration with crypto_engine_unregister_aeads(), but it
passes ARRAY_SIZE(algs), which is the skcipher table size.

Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper
iterates over the same table that was registered.  Also clarify the nearby
comment: the crypto registration helpers clean up algorithms registered
within the same call, while this function must still unwind earlier
successful registration steps.
