i3c: dw: fix slave device setup after DAA

i3c_master_add_i3c_dev_locked() incorrectly set master->this to the
newly discovered slave device, causing i3c_master_attach_i3c_dev()
to skip the attach_i3c_dev() callback. As a result the slave device
never got its master_priv (DAT slot index) allocated, free_pos was
never updated, and the DAT entry was never written.

Fix by removing the incorrect master->this assignment. Store the
slave descriptor directly in master->i3cdev[pos] inside
dw_i3c_master_attach_i3c_dev() where the DAT slot index is already
known. Also check the return value of i3c_master_add_i3c_dev_locked()
and skip num_i3cdevs increment on failure, fixing dummy devices shown
when no slaves are present on the bus.
