This series fixes several leaks in Vhost-user requests
handling.

Thanks to Xuan Ding from Intel for reporting these
issues.

Changes in v2:
- Fix typos in commit messages. (Chenbo)
- Remove useless closing of fds inset_log_base. (Chenbo)

Maxime Coquelin (3):
  vhost: fix error path when setting memory tables
  vhost: fix fd leak in dirty logging setup
  vhost: fix fd leak in kick setup

If an error is encountered before the memory regions are
parsed, the file descriptors for these shared buffers are
leaked.

This patch fixes this by closing the message file descriptors
on error, taking care of avoiding double closing of the file
descriptors. guest_pages is also freed, even though it was not
leaked as its pointer was not overridden on subsequent function
calls.

Fixes: 8f972312b8f4 ("vhost: support vhost-user")
Cc: stable@dpdk.org

I remember we have agreed on simply return here? As I look back to v1, I think
you may modify the wrong place. Because I see another 'goto close_msg_fds' is
deleted compared with v1 😊.

 	if (msg->size != sizeof(VhostUserLog)) {
 		VHOST_LOG_CONFIG(ERR,

... I need more coffee it seems! Of course you are right, I reverted the
wrong line. Thanks for catching it.

v3 on its way.
