    hw/vfio: cpr-iommufd: Fix wrong usage of migrate_add_blocker_modes

    The return value of API is 0 for success and negative error code for
    failure. We'll check if the return value equals to 0.
    Also, the MIG_MODE should be CPR_TRANSFER and CPR_EXEC instead
    of 2 same bits.

    The API usage is aligned with 'hw/vfio/cpr-legacy.c' after these 2
    changes.

    Fixes: 3ca0a0ab05c ("migration: Use bitset of MigMode instead of variable arguments")
