[dpdk-dev] [PATCH] enic: Fixed possible data loss in vnic_dev.c

[Maciej Gajdzica <maciejx.t.gajdzica@intel.com>]

Macro GET_CONFIG passes result of sizeof operation to the function
vnic_dev_spec. This function expects parameter of type unsigned int.
Changed that parameter type to size_t in function declaration to prevent
possible data loss. Issue found with static code analysis tool.
