[Qemu-trivial] [PATCH] migration: fix missing assignment for has_x_checkpoint_delay

[zhanghailiang]

We forgot to assign true to params->has_x_checkpoint_delay parameter
in qmp_query_migrate_parameters.

Without this, qmp command 'query-migrate-parameters' doesn't show the
default value for x-checkpoint-delay option.
It doesn't influence output of hmp command 'info migrate_parameters'.
