Linus Torvalds bd2049f871 A single fix for the fallout of the recent futex uacess rework.

With those changes GCC9 fails to analyze arch_futex_atomic_op_inuser()
 correctly and emits a 'maybe unitialized' warning. While we usually ignore
 compiler stupidity the conditional store is pointless anyway because the
 correct case has to store. For the fault case the extra store does no harm.
