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.
