scsi: be2iscsi: Fix checks for HBA in error state
Save ue_detected and fw_timeout errors in state field of beiscsi_hba. BEISCSI_HBA_RUNNING BEISCSI_HBA_LINK_UP BEISCSI_HBA_BOOT_FOUND BEISCSI_HBA_PCI_ERR BEISCSI_HBA_FW_TIMEOUT BEISCSI_HBA_IN_UE Make sure no PCI transaction happens once in error state. Add checks in IO path to detect HBA in error. Skip hwi_purge_eq step which can't be done in error state.
