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

if of_find_device_by_node() succeed, imx_es8328_probe() doesn't have
a corresponding put_device(). Thus add a jump target to fix the exception
handling for this function implementation.

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