scsi: hisi_sas: check PHY state in get_wideport_bitmap_v3_hw()
We should check register PHY_STATE when getting the bitmap of a wideport, as, if the PHY is not ready, the value of register PHY_PORT_NUM_MA is not valid. V2 hw has done this check, and v3 hw should do this check too. Signed-off-by: Xiaofei Tan <tanxiaofei@huawei.com> Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K.
