icE1usb fw: Workaround some apparent GCC aliasing bug ...

If the code is built either :
 * without -flto
 * with -fno-strict-aliasing
 * with that struct as 'static' (so it's not on the stack)

Then all works fine. But in the current situation (without the
patch), GCC seems to think there is some aliasing and just plain
removed the `notif.bits = 1` bit of code in that functions
(no warnings printed ...).

Putting the struct as 'static' is the least awful workaround.

I didn't bother reporting bug upstream, because I can't reproduce
on a small test case and I'm sure I'd just get yelled at and that
the compiler is right for some reason ...
