scsi: megaraid_sas: fix error handle in megasas_probe_one
megasas_mgmt_info.max_index has increased by 1 before megasas_io_attach, if megasas_io_attach return error, then goto fail_io_attach, megasas_mgmt_info.instance has a wrong index here. So first reduce max_index and then set that instance to NULL. Signed-off-by: weiping zhang <zhangweiping@didichuxing.com> Acked-by: Sumit Saxena <sumit.saxena@broadcom.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
