media: i2c: dw9714: Disable the regulator when the driver fails to probe

When the driver fails to probe, we will get the following splat:

[   59.305988] ------------[ cut here ]------------
[   59.306417] WARNING: CPU: 2 PID: 395 at drivers/regulator/core.c:2257 _regulator_put+0x3ec/0x4e0

Fix this by disabling the regulator in error handling.
