scsi: qla2xxx: Fix N2N inconsistent PLOGI

Browse Source 
For N2N topology, ELS Passthrough is used to send PLOGI. On failure of ELS
pass through PLOGI, driver flipped over to using LLIOCB PLOGI for N2N. This
is not consistent. Delete the session to restart the connection where ELS
pass through PLOGI would be used consistently.
