[PATCH] io: accel: kxcjk1013 Fix missing unlock errors

[Srinivas Pandruvada]

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
