Nathan Chancellor ea3bff7a26 crypto: crypto4xx - Replace bitwise OR with logical OR in crypto4xx_build_pd
[ Upstream commit 5bdad829c31a09069fd508534f03c2ea1576ac75 ]

Clang warns:

                 (crypto_tfm_alg_type(req->tfm) == CRYPTO_ALG_TYPE_AEAD) ?

It looks like this should have been a logical OR so that
PD_CTL_HASH_FINAL gets added to the w bitmask if crypto_tfm_alg_type
is either CRYPTO_ALG_TYPE_AHASH or CRYPTO_ALG_TYPE_AEAD. Change the
operator so that everything works properly.
