migration: use "" instead of (null) for tls-authz
run:
(qemu) info migrate_parameters

...
announce-max: 550 ms

 tls-authz: '(null)'

Migration parameter 'tls-authz' is used to provide the QOM ID
of a QAuthZ subclass instance that provides the access control
check, default is NULL. But the empty string is not a valid
object ID, so use "" instead of the default. Although it will
fail when lookup an object with ID "", it is harmless, just
consistent with tls_creds.

As a bonus, this patch also fixed the bad indentation on the
last line and removed 'has_tls_authz' redundant check in
'hmp_info_migrate_parameters'.
