[PATCH v3 09/12] iio: magnetometer: Remove redundant pm_runtime_mark_last_busy() calls

[Sakari Ailus <sakari.ailus@linux.intel.com>]

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

Also drop checking for errors on pm_runtime_put_autosuspend() in
bmc150_magn_set_power_state().
