Modern memory mode allowes to not reserve any memory by the
'--socket-mem' option. i.e. it could be possible to specify
zero preallocated memory like '--socket-mem 0'.
Also, it should be possible to configure unlimited memory
allocations by '--socket-limit 0'.
Both cases are impossible now and blocks starting the DPDK
application:
./dpdk-app --socket-limit 0 <...>
EAL: invalid parameters for --socket-limit
EAL: Invalid 'command line' arguments.
Unable to initialize DPDK: Invalid argument
Fixes: 6b42f75632f0 ("eal: enable non-legacy memory mode")
