This reverts commit 593a084afc2b441895aeca78a2c4465e450d0ef5. Since recently [1], it is not possible to run the dpdk with non-root privileges and the --no-huge option. This is because the eal layer tries to lock the memory. Using locked memory is mandatory for physical devices because they reference physical addresses. But a user may want to start the dpdk without locked memory, because he does not have the permission to do so, and/or does not have this need, for instance because he uses virtual drivers. So this commit reverts the use of MAP_LOCKED in mmap() flags.

Applied, thanks Let's keep in mind to make things working with --no-huge.
