iio: accel: kxcjk1013 Fix missing unlock errors

Fix unlock at two places. One when i2c error occurs and other
when trigger set state when raw read is in progress.

kbuild test robot errors:
>> >> drivers/iio/accel/kxcjk-1013.c:531:3-9: preceding lock on line 524
>> >> drivers/iio/accel/kxcjk-1013.c:376:4-10: preceding lock on line 368
