cifs: fix potential null pointer use in destroy_workqueue in init_cifs error path

Browse source

Dan Carpenter reported a Smack static checker warning:
   fs/smb/client/cifsfs.c:1981 init_cifs()
   error: we previously assumed 'serverclose_wq' could be null (see line 1895)

The patch which introduced the serverclose workqueue used the wrong
oredering in error paths in init_cifs() for freeing it on errors.

Fixes: 173217bd73 ("smb3: retrying on failed server close")
