Currently we will call `rte_vhost_vring_call` in the DPDK
"vhost-events" thread context when starting the device, and
DPDK vhost library already holds all VQ's access lock when
starting device, with new DPDK/dpdk@c573699 commit, it will
cause deadlock to call `rte_vhost_vring_call` in "vhost-events"
context, so here we increase 1 to `used_req_cnt` to make sure
one more `rte_vhost_vring_call` will be executed later in SPDK
thread context.
