i3c: master: Fix SETDASA process 



When a I3C DT node has a static_addr and an init_dyn_addr,the
init_dyn_addr is reserved in i3c_master_bus_init() and then
the static_addr is reserved in i3c_master_early_i3c_dev_add().
But if the dynamic address is same as static then above
procedure would fail.
Add a check to pass i3c_bus_get_addr_slot_status() when static
and dynamic address are equal.
