[PATCH] staging: IIO: DAC: Delete useless label error_ret in ad5791.c

[stufever]

From: Wang Shaoyan <wangshaoyan.pt@xxxxxxxxxx>

  drivers/staging/iio/dac/ad5791.c: In function 'ad5791_probe':
  drivers/staging/iio/dac/ad5791.c:384: warning: label 'error_ret' defined but not used

The label error_ret is defined, but never used, so delete it to avoid annoying warning.
