[stable-only][ovn-octavia-provider] Multiple listener-pool-member on IPv6 LB getting second pool in ERROR

[Fernando Royo]

When an LB IPv6 is created using a bulk command or when multiple listener-pool-member are added sequentially, the second listener-pool managed fails when adding a member, resulting in the pool's state being in an ERROR state.

The error in traceback is:

2024-02-07 12:40:56.166 13 ERROR networking_ovn.octavia.ovn_driver Traceback (most recent call last):

So apparently, the LB_VIP is enclosed in additional brackets [ ] when adding the member to the second listener-pool-member.

This issue is only occurring in stable branches.
