x86: Use helpers for rlimits
Make sure compiler won't do weird things with limits. Fetching them
twice may return 2 different values after writable limits are
implemented.
We can either use rlimit helpers added in
3e10e716abf3c71bdb5d86b8f507f9e72236c9cd or ACCESS_ONCE if not
applicable; this patch uses the helpers.
