eal: fix enabled core number with -l option

When using core list argument to define which core to enable (ie -l) the
core_num field of the rte configuration is not updated the same way as using
coremask. This causes rte_lcore_num() to yield different value from the one
using coremask.

Fixes: d888cb8b9613 ("add core list input format")
