In the Linux kernel, the following vulnerability has been resolved:

cifs: Fix lost destroy smbd connection when MR allocate failed

If the MR allocate failed, the smb direct connection info is NULL,
then smbd_destroy() will directly return, then the connection info
will be leaked.

Let's set the smb direct connection info to the server before call
smbd_destroy().
