From: Tonghao Zhang <xiangxia.m....@gmail.com>
When first call the 'rte_vhost_driver_start', the
fdset_event_dispatch thread should be created successfully.
Because the vhost uses it to poll socket events for vhost
server or clients. Without it, for example, vhost will not
get the connection event.
This patch returns err code directly when created not successful.

According to rte_vhost_driver_start doc, replace the err code
of pthread_create with -1.
