Ensure that the bad duplicates reported by the platform firmware doesn't

Hi Sibi,

so if the idea is to make the code more robust when FW sends BAD
duplicates, you necessarily need to properly drop opps in opp_count too.

One other option would be to just loop with xa_for_each BUT opp_count is
used in a number of places...so first of all let's try drop count properly.

Can you try this patch down below, instead of your patch.
If it solves, I will send a patch (after testing it a bit more :D)

Hold on... I sent you a diff that does not apply probably on your tree due
to some uncomitted local work of mine...my bad...let me resend.

Hey Cristian,
Thanks for taking time to send out the diff. I thought this would be
enough but there will still be a disconnect between opp_count and idx
of the opp we populate. Consider a case were we get to have a valid
opp just after duplicate opp. The opp_count will still limit us on what
levels we are allowed to see.

Thanks,
Cristian
