ASoC: cs35l56: Fix wrong error test on simple_write_to_buffer()

In cs35l56_cal_data_debugfs_write() fix the if statement that checks for
error return to only check for negative values.

Reported by Sashiko:

  simple_write_to_buffer() returns the positive number of bytes copied
  on success. Since the condition returns immediately on any non-zero
  value, is it possible that the written calibration data is discarded
  and cs35l56_stash_calibration() is never called?
