hwsim: fix early bail out processing rules

If a rule was disabled it would cause hwsim to not continue processing
frames using rules further in the queue. _Most_ tests only use one
rule so this shouldn't have changed their behavior but others which
use multiple rules may be effected and the tests have not been
running properly.
