Subject: [PATCH] cifs: Fix lost destroy smbd connection when MR allocate
failed
Git-commit: e9d3401d95d62a9531082cd2453ed42f2740e3fd
References: git-fixes
Patch-mainline: v6.3-rc1
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().
