atomics/treewide: Make atomic64_inc_not_zero() optional
We define a trivial fallback for atomic_inc_not_zero(), but don't do the same for atomic64_inc_not_zero(), leading most architectures to define the same boilerplate. Let's add a fallback in <linux/atomic.h>, and remove the redundant implementations. Note that atomic64_add_unless() is always defined in <linux/atomic.h>, and promotes its arguments to the requisite types, so we need not do this explicitly. There should be no functional change as a result of this patch.
