env/dpdk: allow 0 requested memory size 



Now that DPDK can reserve additional memory on the fly,
the initial requested memory only serves as preallocation
and it makes sense to request no preallocated memory.

Right now, passing `--mem-size 0` counterintuitively
tries to reserve all hugepages on the system.
