Subject: [PATCH 3/5] crypto: chacha20 - Remove cra_alignmask

From: Eric Biggers <ebiggers@...gle.com>

Now that crypto_chacha20_setkey() and crypto_chacha20_init() use the
unaligned access macros and crypto_xor() also accepts unaligned buffers,
there is no need to have a cra_alignmask set for chacha20-generic.
