i3c: master: Fix missing 'ret' assignment in set_speed()
Fix a probe failure in the i3c master driver that occurs when no i3c devices are connected to the bus. The issue arises in `i3c_master_bus_init()` where the `ret` value is not updated after calling `master->ops->set_speed()`. If no devices are present, `ret` remains set to `I3C_ERROR_M2`, causing the code to incorrectly proceed to `err_bus_cleanup`.
