netfilter: xt_quota: Don't use aligned attribute in sizeof

Clang warns:

net/netfilter/xt_quota.c:47:44: warning: 'aligned' attribute ignored when parsing type [-Wignored-attributes]

        BUILD_BUG_ON(sizeof(atomic64_t) != sizeof(__aligned_u64));
                                                  ^~~~~~~~~~~~~

Use 'sizeof(__u64)' instead, as the alignment doesn't affect the size of the type.

Applied, thanks.
