Kees Cook 09b69dd437 usb: ch9: Replace 1-element array with flexible array 
Since commit df8fc4e934 ("kbuild: Enable -fstrict-flex-arrays=3"),
UBSAN_BOUNDS no longer pretends 1-element arrays are unbounded. Walking
wData will trigger a warning, so make it a proper flexible array. Add a
union to keep the struct size identical for userspace in case anything
was depending on the old size.
