[PATCH] iio: accel: kxcjk-1013: disable autosuspend on remove

[Guangshuo Li]

kxcjk1013_probe() enables runtime PM autosuspend with
pm_runtime_use_autosuspend(). The probe error path correctly undoes
this setting with pm_runtime_dont_use_autosuspend(), but the normal
remove path only disables runtime PM.

The runtime PM API requires pm_runtime_use_autosuspend() to be undone
with pm_runtime_dont_use_autosuspend() at driver exit unless runtime PM
was enabled with devm_pm_runtime_enable(). Leaving the autosuspend flag
set therefore leaves the runtime PM state incompletely cleaned up after
the driver is unbound.

Add the missing pm_runtime_dont_use_autosuspend() call to the remove
path.

This issue was found by manual code inspection.
