Shouldn't this be REG10[7]?

Because we share the same ovn_lb structure between NB and SB we're now forced
to parse the backend IP twice:
ovn_sb_lb_create()
- ovn_lb_create()
-- ip_address_and_port_from_key()
--- this parses the string into a sockaddr_storage
--- then builds an IP string and extracts the port
Here we reparse the IP string into an ovs_be32.
If the structs were independent for NB/SB I think we would pottentially have
simpler code and we would avoid reparsing IPs.
Also, what if the SB DB gets corrupted, do we really want ovn-controller to
abort?

Indentation is a bit odd.

As mentioned above for backends, I don't think it's OK to abort here if parsing
fails.

Setting the flags here is not needed anymore if we set the value when we
ofpact_put_CT().

Nit: we could avoid 'consider_lb' by:

For consistency, shouldn't we add logs for the non incremental processing case
too?
