USB: fix build error with CONFIG_PM_RUNTIME disabled
commit a9ef803d740bfadf5e505fbc57efa57692e27025 upstream. commit bdd405d2a528 ("usb: hub: Prevent hub autosuspend if usbcore.autosuspend is -1") causes a build error if CONFIG_PM_RUNTIME is disabled. Fix that by doing a simple #ifdef guard around it.
