The reattach should be used when an I3C device has its address changed.
But the modified place in this patch doesn't have the address changed of
the newdev. This wrong reattach will reserve the same address slot twice
and return unexpected -EBUSY when the bus find the duplicate device with
diffent dynamic address.
