Subject: scsi: qla2xxx: Fix N2N inconsistent PLOGI
Patch-mainline: v5.18-rc1
Git-commit: c13ce47c64ea8f14e77eecb40d1e7c2ac667f898
References: bsc#1197661

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.
