ENGR00325203 usb: chipidea: host: check if ci->hcd initialized before access it
When ci core driver enable runtime pm in probe, it's possible runtime suspend
will be started before otg fsm queue work get to run, in this case, host has not
been started yet so ci->hcd is NULL, but suspend routine will access it for save
ehci registers, which result in kernle panic, this patch adds pointer valid check.
