PCI: dwc: Remove LTSSM state test in dw_pcie_suspend_noirq()
It's safe to send PME_TURN_OFF message regardless of whether the link is up
or down, so don't test the LTSSM state before sending the PME_TURN_OFF
message.
Only print an error message when the LTSSM is not in DETECT or POLL. There
shouldn't be an error when no Endpoint is connected at all.
