    migration: fix spice migration

    Commit 29ae8a4133082e16970c9d4be09f4b6a15034617 ("rdma: introduce
    MIG_STATE_NONE and change MIG_STATE_SETUP state transition") changed the
    state transitions during migration setup.

    Spice used to be notified with MIG_STATE_ACTIVE and it detected this
    using migration_is_active().  Spice is now notified with
    MIG_STATE_SETUP and migration_is_active() no longer works.

    Replace migration_is_active() with migration_in_setup() to fix spice
    migration.
