There are situations during the xhci_resume() sequence, which allows for
re-initializing of the XHCI HC.  However, in case the HCD is being removed,
these operations may not be needed.  Set the removal state before issuing
the runtime PM get on the XHCI device, so that the XHCI resume routine will
know when to bypass the re-init logic.
