[unifi] Fix bug with combination of other data/ports (#14060)

- It seems to throw an exception when updating internal cache. It can happen if you have a switch that has both PoE ports and other PoE ports or data in the port override.
- Fixed logout, should be POST instead of GET.
- Fixed typo in channel-type.config.unifi.poeEnable.mode.option.pasv24 should be without appending v.
- Removed compiler warnings.
