x86/irqflags: Provide a declaration for native_save_fl
It was reported that the commit d0a8d9378d16 is causing users of gcc < 4.9
to observe -Werror=missing-prototypes errors.
Indeed, it seems that:
extern inline unsigned long native_save_fl(void) { return 0; }
compiled with -Werror=missing-prototypes produces this warning in gcc <
4.9, but not gcc >= 4.9.
Fixes: d0a8d9378d16 ("x86/paravirt: Make native_save_fl() extern inline").
