vhost-user: Skip unnecessary duplicated VHOST_USER_SET_LOG_BASE requests

Browse Source 
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.
