Sudip Mukherjee d32d6d2bee tty: always relink the port 
commit 273f632912 upstream.

If the serial device is disconnected and reconnected, it re-enumerates
properly but does not link it. fwiw, linking means just saving the port
index, so allow it always as there is no harm in saving the same value
again even if it tries to relink with the same port.

Fixes: fb2b90014d ("tty: link tty and port before configuring it as console")
