iio: adc: twl4030: Disable the vusb3v1 rugulator in the error handling path of 'twl4030_madc_probe()'
commit 7f70be6e4025db0551e6863e7eb9cca07122695c upstream.
Commit 7cc97d77ee8a has introduced a call to 'regulator_disable()' in the
.remove function.
So we should also have such a call in the .probe function in case of
error after a successful 'regulator_enable()' call.
Add a new label for that and use it.
