[PATCH] aio: don't ref kioctx after decref in put_ioctx
put_ioctx's refcount debugging was doing an atomic_read after dropping its
reference when it wasn't the last ref, leaving a tiny race for another freeing
thread to sneak into. This shifts the debugging before the ops, uses BUG_ON,
and reformats the defines a little. Sadly, moving to inlines increased the
code size but this change decreases the code size by a whole 9 bytes :)
