[PATCH v5 3/5] media: imx-jpeg: Cleanup after an allocation error

[ming.qian@oss.nxp.com]

From: Ming Qian <ming.qian@oss.nxp.com>

When allocation failures are not cleaned up by the driver, further
allocation errors will be false-positives, which will cause buffers to
remain uninitialized and cause NULL pointer dereferences.
Ensure proper cleanup of failed allocations to prevent these issues.

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