i3c: Fix unlocked dereference of dev->desc in i3c_device_get_supported_xfer_mode()

In the Linux kernel, the following vulnerability has been resolved:

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.
