usb: hide unused usbfs_notify_suspend/resume functions 



The declaration is in an #ifdef, which causes warnings when building
with 'make W=1' and without CONFIG_PM:

drivers/usb/core/devio.c:742:6: error: no previous prototype for 'usbfs_notify_suspend'
drivers/usb/core/devio.c:747:6: error: no previous prototype for 'usbfs_notify_resume'

Use the same #ifdef check around the function definitions to avoid
the warnings and slightly shrink the USB core.
