Revert "i3c master: fix missing destroy_workqueue() on error in i3c_master_register"

Adding the destroy_workqueue call in i3c_master_register introduced below
kernel warning because it makes duplicate destroy_workqueue calls when
i3c_master_register fails after allocating the workqueue. The workqueue will
be destroyed by i3c_masterdev_release which is called by put_device at the
end of the i3c_master_register function eventually in failure cases so the
workqueue doesn't need to be destroyed in i3c_master_register.
