usb: raw_gadget: fix compilation warnings in uapi headers

Mark usb_raw_io_flags_valid() and usb_raw_io_flags_zero() as inline to
fix the following warnings:

./usr/include/linux/usb/raw_gadget.h:69:12: warning: unused function 'usb_raw_io_flags_valid' [-Wunused-function]
./usr/include/linux/usb/raw_gadget.h:74:12: warning: unused function 'usb_raw_io_flags_zero' [-Wunused-function]
