If vcap_dup_rule() fails that leads to an error pointer dereference
side the call to vcap_free_rule(). Also it only returns an error if the
very last call to vcap_read_rule() fails and it returns success for
other errors.
I've changed it to just stop printing after the first error and return
an error code.
