nat: fix byte order on ipfix message fields
Type: fix The code for quota exceeded events is a u32 and was being copied into ipfix packets in host byte order. Same for the limit field. Swap the order before copying into packet buffer. This change was applied once before but had to be reverted. This was because between the time the change was uploaded/reviewed and the time it was merged, a different patch was merged which activated a NAT ipfix unit test that had formerly only been run as part of the extended tests. The test was expecting the values to be in host byte order so it failed with this patch applied. This time around, that test has also been updated to expect network byte order.
