thermal: exynos: Disable the regulator on probe failure
commit 5f09a5cbd14ae16e93866040fa44d930ff885650 upstream.
During probe the regulator (if present) was enabled but not disabled in
case of failure. So an unsuccessful probe lead to enabling the
regulator which was actually not needed because the device was not
enabled.
Additionally each deferred probe lead to increase of regulator enable
count so it would not be effectively disabled during removal of the
device.
Test HW: Exynos4412 - Trats2 board
