macintosh/hwmon/ams: Fix device removal sequence
Some code that is in ams_exit() (the module exit code) should instead
be called when the device (not module) is removed. It probably doesn't
make much of a difference in the PMU case, but in the I2C case it does
matter.
I make no guarantee that my fix isn't racy, I'm not familiar enough
with the ams driver code to tell for sure.
