iio: hid-sensor: Fix unbalanced pm_runtime_enable error
When a hid sensor module is removed and modprobed again we see error for unbalanced pm_runtime. This issue is caused by not deactivating runtime PM on removal. So on modprobe again when activated again, this will print this error. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
