media: imx-jpeg: Cleanup after an allocation error

commit 7500bb9cf164edbb2c8117d57620227b1a4a8369 upstream.

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.
