When --no-huge mode is used, the memory is currently allocated with
mmap(NULL, ...). This is fine in most cases, but can fail in cases
where DPDK is run on a machine with an IOMMU that is of more limited
address width than that of a VA, because we're not specifying the
address hint for mmap() call.
Fix it by preallocating VA space before mapping it.

Reproduced issue reported by Thomas on v2.
Works fine with v3.

Does this issue affect FreeBSD too?
I don't think we have support for IOMMU on FreeBSD so my guess is no :)
