Frank Li c704ccb558 i3c: fix refcount inconsistency in i3c_master_register
[ Upstream commit 9d4f219807d5ac11fb1d596e4ddb09336b040067 ]

In `i3c_master_register`, a possible refcount inconsistency has been
identified, causing possible resource leak.

Function `of_node_get` increases the refcount of `parent->of_node`. If
function `i3c_bus_init` fails, the function returns immediately without
a corresponding decrease, resulting in an inconsistent refcounter.

Move call i3c_bus_init() after device_initialize() to let callback
i3c_masterdev_release() release of_node.
