cifs: Fix lost destroy smbd connection when MR allocate failed

Browse Source 
[ Upstream commit e9d3401d95d62a9531082cd2453ed42f2740e3fd ]

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().
