atomics/treewide: Remove redundant atomic_inc_not_zero() definitions
When atomic_inc_not_zero(v) isn't defined, <linux/atomic.h> will define it as falling back to atomic_add_unless((v), 1, 0), so there's no need for arch code to do so. There should be no functional change as a result of this patch.
