fix minor infoleak in get_user_ex()
commit 1c109fabbd51863475cd12ac206bdd249aee35af upstream.
get_user_ex(x, ptr) should zero x on failure. It's not a lot of a leak
(at most we are leaking uninitialized 64bit value off the kernel stack,
and in a fairly constrained situation, at that), but the fix is trivial,
so...
