Jamie Iles 1e3ed66673 i3c: fix uninitialized variable use in i2c setup 
[ Upstream commit 6cbf8b38df ]

Commit 31b9887c72 ("i3c: remove i2c board info from i2c_dev_desc")
removed the boardinfo from i2c_dev_desc to decouple device enumeration from
setup but did not correctly lookup the i2c_dev_desc to store the new
device, instead dereferencing an uninitialized variable.

Lookup the device that has already been registered by address to store
the i2c client device.

Fixes: 31b9887c72 ("i3c: remove i2c board info from i2c_dev_desc")
