From: Joe Eykholt <jeykholt@xxxxxxxxx>
State RPORT_ST_NONE was intented to be an invalid state (0), never used.
This was a misguided attempt to be sure it was always initialized.
Having an extra state meaning nothing requires switch statements to
have a case covering that state.
State NONE has been used instead to mean the remote port is being deleted.
Changing the name to RPORT_ST_DELETE.
