[PATCH] lib/crypto: aes-gcm: Fix CRYPTO_LIB_GF128HASH selection

[PATCH] lib/crypto: aes-gcm: Fix CRYPTO_LIB_GF128HASH selection

[Eric Biggers]

Move the selection of CRYPTO_LIB_GF128HASH from CRYPTO_LIB_AES_GCM to
CRYPTO_LIB_AES to avoid a build error when CRYPTO_LIB_AES=y &&
CRYPTO_LIB_AES_GCM=m.  Like the other AES modes, AES-GCM is included in
libaes as an optional feature rather than a dedicated module.
