[dpdk-dev] [PATCH v2 04/25] eal: do not panic on failed hugepage query

[Aaron Conole <aconole@redhat.com>]

If we fail to acquire hugepage information, simply signal an error to
the application.  This clears the run_once counter, allowing the user or
application to take a corrective action and retry.
