    cluster/ec: Fix use after free crash

    ec_heal creates ec_fop_data but doesn't run ec_manager.
ec_fop_data_allocate
    adds this fop to ec->pending_fops, because ec_manager is not run on this
heal
    fop it is never removed from ec->pending_fops. When it is accessed after
free
    it leads to crash. It is better to not to add HEAL fops to ec->pending_fops
    because we don't want graph switch to hang the mount because of a BIG
    file/directory heal.
