Subject: [PATCH] vhost-user: Skip unnecessary duplicated
 VHOST_USER_SET_LOG_BASE requests

The VHOST_USER_SET_LOG_BASE requests should be categorized into
non-vring specific messages, and should be sent only once.
If send more than once, dpdk will munmap old log_addr which may has been used
and cause segmentation fault.
