Reader/writer locks are significantly more expensive than simple
spin lock. Even uncontended access requires additional cache update.
Unless there is case with a long region where lock is held,
just use a spin lock.
See some Paul McKenney's locking talks (LCA video is good) about
lock overheads in Linux. Since DPDK has same set of instructions
to use; the same issues apply to userspace.
