iio: Fix error handling for PM
commit 632fe0bb8c5b9c06ec961f575ee42a6fff5eceeb upstream.
The pm_runtime_enable will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable(). In the PM Runtime docs:
Drivers in ->remove() callback should undo the runtime PM changes done
in ->probe(). Usually this means calling pm_runtime_disable(),
pm_runtime_dont_use_autosuspend() etc.
We should do this in error handling.
Fix this problem for the following drivers: bmc150, bmg160, kmx61,
kxcj-1013, mma9551, mma9553.
Fixes: 7d0ead5c3f00 ("iio: Reconcile operation order between iio_register/unregister and pm functions")
