This reverts commit 593a084afc.
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.
