DVR: Look at all SNAT ports for a subnet match
For IPv6, the csnat port list could have multiple
subnets contained in it, but we were only ever
looking at the one associated with the first fixed
IP when trying to match an internal port. Change
to check all subnets on all port combinations
(internal and csnat) before giving up.

DVR: SNAT port not found in the list error in check jobs
Status in neutron:
Fix Released
Bug description:
While looking through logs I came across this ERROR:

Pasting here since that log could go away (even if the paste is
horribly wrapped, but tried to format it a little):

From looking at the trace, I do see the subnet in question in the
list, but since the code is only checking it's in the first port it
doesn't find it. I'm curious why it doesn't look in them all, so will
propose a patch to verify it works and get some feedback.
