iio: adc: ad799x: fix probe error handling

commit c62dd44901cfff12acc5792bf3d2dec20bcaf392 upstream.

Since commit 0f7ddcc1bff1 ("iio:adc:ad799x: Write default config on probe
and reset alert status on probe") the error path is wrong since it
leaves the vref regulator on. Fix this by disabling both regulators.
