usb: ehci-exynos: Return immediately from suspend if ehci_suspend fails
Patch 'b8efdaf USB: EHCI: add check for wakeup/suspend race' adds a check for possible race between suspend and wakeup interrupt, and thereby it returns -EBUSY as error code if there's a wakeup interrupt. So the platform host controller should not proceed further with its suspend callback, rather should return immediately to avoid powering down the essential things, like phy.
