ec/fini: Fix race between xlator cleanup and on going async fop
Problem:
While we process a cleanup, there is a chance for a race between
async operations, for example ec_launch_replace_heal. So this can
lead to invalid mem access.
Solution:
Just like we track on going heal fops, we can also track fops like
ec_launch_replace_heal, so that we can decide when to send a
PARENT_DOWN request.
