crypto: lrw - use correct alignmask
Commit c778f96bf347 ("crypto: lrw - Optimize tweak computation")
incorrectly reduced the alignmask of LRW instances from
'__alignof__(u64) - 1' to '__alignof__(__be32) - 1'.
However, xor_tweak() and setkey() assume that the data and key,
respectively, are aligned to 'be128', which has u64 alignment.
Fix the alignmask to be at least '__alignof__(be128) - 1'.
