ASoC: cs4271: Fix regulator leak on probe failure

Browse source

[ Upstream commit 6b6eddc63c ]

The probe function enables regulators at the beginning
but fails to disable them in its error handling path.
If any operation after enabling the regulators fails,
the probe will exit with an error, leaving the regulators
permanently enabled, which could lead to a resource leak.

Add a proper error handling path to call regulator_bulk_disable()
before returning an error.
