Subject: [PATCH V2 2/3] mfd: wm8994-core: disable regulators before removing them

The order in which resources were freed in wm8994_device_exit() isn't
correct. The regulators are removed before they are disabled.

Fix it by reordering code a bit, which makes it exact opposite of
wm8994_device_init() as well.
