usb: host: xhci: move HC_STATE_SUSPENDED check to xhci_suspend()
that check will have to be done by all users of xhci_suspend() so it sounds a lot better to move the check to xhci_suspend() in order to avoid code duplication. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
