X-Git-Tag: v9.1.0-rc0~46^2~41

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.
