nwfilter: remove unnecessary code from ebtablesGetSubChainInsts()

On failure, this function would clear out and free the list of
subchains it had been called with. This is unnecessary, because the
*only* caller of this function will also clear out and free the list
of subchains if it gets a failure from ebtablesGetSubChainInsts().

(It also makes more logical sense for the function that is creating
the entire list to be the one freeing the entire list, rather than
having a function whose purpose is only to create *one item* on the
list freeing the entire list).
