[PATCH -next] media: imx-jpeg: Fix error return code in mxc_jpeg_probe()

['w00385741]

From: Wei Yongjun <weiyongjun1 at huawei.com>

Fix to return negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 2db16c6ed72c ("media: imx-jpeg: Add V4L2 driver for i.MX8 JPEG Encoder/Decoder")
