See attached. Both cc: stable

"cifs: set correct tcon status after initial tree connect"

cifs_tcon::status wasn't correctly updated to TID_GOOD after initial
tree connect thus staying at TID_NEW as long as it was connected.

and

"cifs: set correct ipc status after initial tree connect"

cifs_tcon::status wasn't correctly updated to TID_GOOD after
establishing initial IPC connection thus staying at TID_NEW as long as
it wasn't reconnected.
