migration: Fix migrate-set-parameters argument validation
Commit 741d4086c8 "migration: Use proper types in json" (v2.12.0)
switched MigrationParameters to narrower integer types, and removed
the simplified qmp_migrate_set_parameters()'s argument checking
accordingly.
Good idea, except qmp_migrate_set_parameters() takes
MigrateSetParameters, not MigrationParameters. Its job is updating
migrate_get_current()->parameters (which *is* of type
MigrationParameters) according to its argument. The integers now get
truncated silently. Reproducer:
---> {'execute': 'query-migrate-parameters'}
<--- {"return": {[...] "compress-threads": 8, [...]}}
---> {"execute": "migrate-set-parameters", "arguments": {"compress-threads": 257}}
<--- {"return": {}}
---> {'execute': 'query-migrate-parameters'}
<--- {"return": {[...] "compress-threads": 1, [...]}}
Fix by resynchronizing MigrateSetParameters with MigrationParameters.
