[PATCH 1/2] ASoC: fsl: imx-es8328: add missing kfree() call in imx_es8328_probe()

[Yu Kuai]

If memory allocation for 'data' or 'comp' succeed, imx_es8328_probe()
doesn't have corresponding kfree() in exception handling. Thus add
kfree() for this function implementation.

Fixes: 7e7292dba215 ("ASoC: fsl: add imx-es8328 machine driver")
