closures: Better memory barriers
atomic_(dec|sub)_return_release() are a thing now - use them.
Also, delete the useless barrier in set_closure_fn(): it's redundant
with the memory barrier in closure_put(0.
Since closure_put() would now otherwise just have a release barrier, we
also need a new barrier when the ref hits 0 -
smp_acquire__after_ctrl_dep().
