cifs: fix potential race when tree connecting ipc
commit ee20d7c6100752eaf2409d783f4f1449c29ea33d upstream.
Protect access of TCP_Server_Info::hostname when building the ipc tree
name as it might get freed in cifsd thread and thus causing an
use-after-free bug in __tree_connect_dfs_target(). Also, while at it,
update status of IPC tcon on success and then avoid any extra tree
connects.
