[SCSI] libfc: rename rport state "NONE" to "DELETE".

[SCSI] libfc: rename rport state "NONE" to "DELETE".

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.
