target: remove some smp_mb__after_atomic()s
atomic_inc_return() already does an implicit memory barrier and the
second case was moved from an atomic to a plain flag operation. If a
barrier were needed in the second case, it would have to be smp_mb(),
not a variant optimized away for x86 and other architectures.
