hugepage_reset: removes hugepages setup

As the test will set 8 hugepages, this works fine
for systems with 2 NUMA nodes, having e.g. 8 nodes
is going to lead the on_numa_node variant to fail
since the binded node doesn't have enough hugepages.

As the cfg already suggests to allocate 1G hugepages
on boot time, let's make user decision how many hugepages
allocate, adding an informative comment in the cfg as well.
