net: ethernet: mtk_wed: annotate RCU release in attach() 



There are some sparse warnings in wifi, and it seems that
it's actually possible to annotate a function pointer with
__releases(), making the sparse warnings go away. In a way
that also serves as documentation that rcu_read_unlock()
must be called in the attach method, so add that annotation.
