[dpdk-dev] [PATCH v3] net/i40e: fix compile error

[Qi Zhang <qi.z.zhang@intel.com>]

This patch fix the compile error when RTE_LIBRTE_I40E_RX_ALLOW_BULK_ALLOC
is disabled. fake_mbuf is also required to be initialized and assigned to
additional sw_ring entries for vector PMD.

Fixes: 9ed94e5bb04e ("i40e: add vector Rx")
