ASoC: rt5682: Properly turn off regulators if wrong device ID

When I booted up on a board that had a slightly different codec
stuffed on it, I got this message at bootup:

  rt5682 9-001a: Device with ID register 6749 is not rt5682

That's normal/expected, but what wasn't normal was the splat that I
got after:

  WARNING: CPU: 7 PID: 176 at drivers/regulator/core.c:2151 _regulator_put+0x150/0x158
  pc : _regulator_put+0x150/0x158
  ...
  Call trace:
   _regulator_put+0x150/0x158
   regulator_bulk_free+0x48/0x70
   devm_regulator_bulk_release+0x20/0x2c
   release_nodes+0x1cc/0x244
   devres_release_all+0x44/0x60
   really_probe+0x17c/0x378
   ...

This is because the error paths don't turn off the regulator. Let's
fix that.
