[dpdk-dev] [PATCH v2] net/i40e: fix testpmd setup error when bulk is disabled

[Beilei Xing]

Testpmd failed to start when CONFIG_RTE_LIBRTE_I40E_RX_ALLOW_BULK_ALLOC
is disabled, the root cause is the length of sw_ring and queue are
incorrect with the above configuration.

Fixes: 0be295312966 ("net/i40e: fix compile error")
