regulator: core: Rely on regulator_dev_release to free constraints
As we now free the constraints in regulator_dev_release we will still
call free on the constraints pointer even if we went down an error
path in regulator_register, because it is only allocated after the
device_register. As such we no longer need to free rdev->constraints
on the error paths, so this patch removes said frees.
Fixes: 29f5f4860a8e ("regulator: core: Move more deallocation into class unregister")
