Adjust the positions of 'tls-authz' and 'max-postcopy-bandwidth' in
the fields output by the 'info migrate_parameters' command so that
related fields are next to each other.
For clarity only, no functional changes.
Sample output after this commit:
(qemu) info migrate_parameters
...
max-cpu-throttle: 99
tls-creds: ''
tls-hostname: ''
tls-authz: ''
max-bandwidth: 134217728 bytes/second
avail-switchover-bandwidth: 0 bytes/second
max-postcopy-bandwidth: 0 bytes/second
downtime-limit: 300 ms
...

This can be moved even above "avail-switchover-bandwidth", IMHO.
With that, feel free to take:

I queued it with this change, please shoot if there's objections.
