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.
