scsi: lpfc: Abort outstanding ELS cmds when mailbox timeout error is …
…detected [ Upstream commit 089ea22 ] A mailbox timeout error usually indicates something has gone wrong, and a follow up reset of the HBA is a typical recovery mechanism. Introduce a MBX_TMO_ERR flag to detect such cases and have lpfc_els_flush_cmd abort ELS commands if the MBX_TMO_ERR flag condition was set. This ensures all of the registered SGL resources meant for ELS traffic are not leaked after an HBA reset.
