i3c: Fix unlocked dereference of dev->desc in i3c_device_get_supported_xfer_mode()
i3c_device_get_supported_xfer_mode() uses dev->desc to obtain the
master controller. However, dev->desc must not be dereferenced unless
bus->lock is held, and this function does not take that lock.
The function only needs access to the master controller associated with
the device's bus. Use dev->bus instead, which is always valid for the
lifetime of the device and does not require dereferencing dev->desc.
